help please: set up swap w/o a2sd [pretty stumped at this point]

im trying to set up a linux_swap partition, but i dont want to use apps2sd, nor do i want to use cache2sd.
can someone point me in the right direction?

Just create the linux-swap partition and not the ext partition.

will i have to wipe?
and what is the recommended size?

Does that work now? I know it depends on how you are doing it, but assuming a build with auto apps2sd, the script just looks at partition number and will screw up if you do that. I think cyanogen has made adjustments in his experimental line.

im running cyanogen 4.0.4. will it work?

if the script does that couldnt you create a 1mb ext2/3/4?

You also need to edit the user.conf file.
linux_swap_en=1 # enable(1) or disable(0) linux swap
linux_swap_partition=/dev/block/mmcblk0p2 # swap partition device
The usual setting is mmcblk0p3 but you need to set it to mmcblk0p2 because your linus swap part is going to be 2 instead of 3

This is for swap only with no compcache
#compcache related parameters
compcache{
compcache_en=0 # enable(1) or disable(0) compcache
cc_disksize=32 # Ram swap disksize - any number between 1 to 95 should work
cc_memlimit=18 # Limite the memory usage when backing swap is used
cc_backingswap_en=0 # enable or disable backing swap
cc_backingswap=/dev/block/mmcblk0p2 # pointing to the backingswap partition device
cc_swappiness=60 # default 60
}
#Linux swap parameters
#
# linux swap can only be enabled if cc_backingswap_en is set to "0"
#
linux_swap{
linux_swap_en=1 # enable(1) or disable(0) linux swap
linux_swap_partition=/dev/block/mmcblk0p2 # swap partition device
swappiness=60 # default 60
}

will compcache improve speed while running background applications?
so do i have to create an ext3 partition to put the userconf in there?
wait, where do i put the user.conf file then?

i read around and i think im supposed to put the user.conf file into /system/sd
i also enabled compcache. let me know if that is not advised.
with a 64mb swap

#compcache related parameters
compcache{
compcache_en=1 # enable(1) or disable(0) compcache
cc_disksize=70 # Ram swap disksize - any number between 1 to 95 should work
cc_memlimit=18 # Limite the memory usage when backing swap is used
cc_backingswap_en=0 # enable or disable backing swap
cc_backingswap=/dev/block/mmcblk0p2 # pointing to the backingswap partition device
cc_swappiness=60 # default 60
}
#Linux swap parameters
#
# linux swap can only be enabled if cc_backingswap_en is set to "0"
#
linux_swap{
linux_swap_en=1 # enable(1) or disable(0) linux swap
linux_swap_partition=/dev/block/mmcblk0p2 # swap partition device
swappiness=60 # default 60
}
i have an issue with a boot loop at th eandroid screen now

ok, so, if i dont boot with the sd card inserted, it boots, but then i get to the home screen and it says none of my apps are installed.
so i go to recovery, remove the user.conf file. and same thing
so i restore, and boot with the sd card in. same thing, bootloop.
and now im restoring, but not booting with sd card.
what happened? was i not supposed to enable compcache? or keep the cc_disksize at 32?

so, ive been following this thread

with this a2sd, it doesnt boot:

partition 1 is my fat32 which is whatever 8 gigs minus 64
partition 2 is 64 megs of linux_swap

WOW,
You have completely over complicated this. remove the user.conf file from every location you put it in, remove all partitions and leave it with none, boot in recovery and wipe, then reflash cyan 4.0.4. reboot. everything should be normal with no swap and it should ask you if you want to format the sd card. when you get it working normal post back here.

my whole point is not to wipe, and i dont want a2sd.
wiping and doing what you said above will enable a2sd.

what part of my previous post would enable apps2sd?

if you don't want to wipe, then at least do everything else i posted

ok, i removed all the user.conf and repartitioned my sdcard
now what?

reflash cyan 4.0.4 and boot so it will format the card

what is the make, size, and class of your sdcard?
why no apps2sd?

[Q] how to move dalvik-cache to ext in cm7.1.0 RC5 11.05.20？

milestone 1 on cm7 0.08-11.04.24 7.0.1 , i have one ext3 partition on my sdcard, everything was working fine,
but after upgrading to cm7.1.0 RC0 11.05.03 yesterday , i can't move the dalvik-cache to ext partition any longer.
even if i do this
mv /data/dalvik-cache /sddata/dalvik-cache
ln -s /sd-ext/dalvik-cache/ /data/dalvik-cache
next time phone reboots, it delete my link and create dalvik-cache directory in "internal storage" while not on my ext3 partition
when i boot into OR 3.3 , the ext3 partition is mounted as /sddata
if i boot into phone ui, the ext3 partition is mounted as /sd-ext
i tiried linking to both directory , none of them works
anyone knows how to do it ?
[edit] after updating to 7.1.0 RC5 11.05.20, the file update-07app2ext-dalvik.on.ext.zip provided by zeppelin doesn't work , ahhhhh.

You will need to edit the 07app2ext file in /system/etc/init.d

Yep.
I did this yesterday actually since my internal storage was getting too low for my liking.
From github, the earlier 07app2ext:
Code:
#!/system/bin/sh
if [ "$SD_EXT_DIRECTORY" = "" ];
then
SD_EXT_DIRECTORY=/sd-ext
fi
if [ "`egrep -q $SD_EXT_DIRECTORY /proc/mounts;echo $?`" != "0" ];
then
echo "$SD_EXT_DIRECTORY not mounted.. skipping a2sd"
exit
fi
for dir in app app-private dalvik-cache;do
if [ "`egrep -q \"/data/${dir}\" /proc/mounts;echo $?`" != "0" ];
then
if [ ! -e "${SD_EXT_DIRECTORY}/${dir}" ];
then
install -m 771 -o 1000 -g 1000 -d ${SD_EXT_DIRECTORY}/${dir}
fi
if [ -L "/data/${dir}" ];
then
rm /data/${dir}
install -m 771 -o 1000 -g 1000 -d /data/${dir}
fi
if [ "${dir}" = "dalvik-cache" ];
then
if [ ! -L "/data/${dir}" ];
then
rm -rf /data/${dir}
install -m 771 -o 1000 -g 1000 -d /data/${dir}
fi
fi
if [ "${dir}" = "app" -o "${dir}" = "app-private" ];
then
for app in `find /data/${dir} -type f -iname "*.apk" -o -iname "*.zip"`;do
mv ${app} ${SD_EXT_DIRECTORY}/${dir}/
done
fi
mount -o bind ${SD_EXT_DIRECTORY}/${dir}/ /data/${dir}
fi
done
chmod 755 /system/etc/init.d/07app2ext
chown -R 0.2000 /system/etc/init.d
sleep 1

I just started using s2e from the market, its working so far

It works on MIUI?

I think so.
It's based on CM7, yeah?
If people are using app2ext on MIUI then I'd say yes.
If it has an 07app2ext file, then it's 100% guaranteed.
What I did was I replaced the 07app2ext file in the update zip with the one above so when it gets flashed I don't have to do anything.

It has an 07app2ext file, so a replace with this and my app2ext didnt work anymore...
There is my older app2ext code:
Code:
#!/system/bin/sh
if [ "$SD_EXT_DIRECTORY" = "" ];
then
SD_EXT_DIRECTORY=/sd-ext
fi
if [ "`egrep -q $SD_EXT_DIRECTORY /proc/mounts;echo $?`" != "0" ];
then
echo "$SD_EXT_DIRECTORY not mounted.. skipping a2sd"
exit
fi
if [ -L "/data/dalvik-cache" ];
then
rm /data/dalvik-cache
install -m 771 -o 1000 -g 1000 -d /data/dalvik-cache
fi
if [ -e "${SD_EXT_DIRECTORY}/dalvik-cache" ];
then
rm -rf ${SD_EXT_DIRECTORY}/dalvik-cache
fi
for dir in app app-private;do
if [ "`egrep -q \"/data/${dir}\" /proc/mounts;echo $?`" != "0" ];
then
if [ ! -e "${SD_EXT_DIRECTORY}/${dir}" ];
then
install -m 771 -o 1000 -g 1000 -d ${SD_EXT_DIRECTORY}/${dir}
fi
if [ -L "/data/${dir}" ];
then
rm /data/${dir}
install -m 771 -o 1000 -g 1000 -d /data/${dir}
fi
if [ "${dir}" = "app" -o "${dir}" = "app-private" ];
then
for app in `find /data/${dir} -type f -iname "*.apk" -o -iname "*.zip"`;do
mv ${app} ${SD_EXT_DIRECTORY}/${dir}/
done
fi
mount -o bind ${SD_EXT_DIRECTORY}/${dir}/ /data/${dir}
fi
done

ah... sometimes that happens...
If you were to put that in the MIUI update zip and flash it, it will work.
I don't know why that happens.
When it happened to me I couldnt figure it out either since I made sure the permissions stayed the same. Maybe it would work as a standalone flashable zip but I have never made one.

Zeppe, can you send me your 07app2ext and tell me what permissions it have? I have 500 mb in the ext partition but i can load it to maximum 'cause my internal storage get full. Now i have about 80 apps, and only 22mb left in the internal storage.

Attached.
Permissions are the same as other files in ect/init.d
xxx
xox
ooo
But when I did it manually, it didn't work
edit... try the attached update.zip... it just might work
either way, the file is in there.

BAZINGA! lol!! It works!!! Thanks a lot zeppelin!

heh

zeppelinrox, can I apply this update on CM7 RC10? Is it safe to do it?
I want to move my dalvik cache to ext2 because my internal storage its almost full (less than 20MB free).

Yes its fine.
It's a mod of an overclock flashable zip so when you flash it, it gives an overclock related message.
You can also replace the app2ext script in the cm7 update with the one in this zip file with 7zip and without extracting the cm7 update.
I just leave it in AOR's update folder tho.
So when I flash a rom, I flash this too
Sent from my Milestone using Tapatalk

Thanks for this script, it works perfectly.
I've applied the update from AOR and after move any app from SD to ext2 and reboot, CM7 moves dalvik cache for that apps to ext2.
Now, I suppose any time I update the ROM then before reboot I need to apply this script again.

Yes as an update would probably overwrite this app2ext script

Proper executing of sysctl.conf during boot

Edit: For some strange reason it suddenly works after posting this topic.. :') Delete please
Ok so this is the deal, I'm currently working on broodKernel v1.2 (yes not 1.1 but 1.2) and I've noticed that sysctl.conf isn't loaded in any way, I tried loading it with "sysctl -p" and also with su -c "sysctl -p", both tried it in the kernel itself and in init.d scripts, for some reason it doesn't load on boot, but when I load it myself with "su -c "sysctl -p" it works correctly :silly:
mode is: 644, also tried to chown it to system and/or root, both didn't work. then I question myself. is my init.d method correct? Is it running in root mode? I use this:
Code:
service initd /system/bin/logwrapper /system/xbin/busybox run-parts /system/etc/init.d
oneshot
doesn't it need a "user root" at the bottom?, I feel kinda like this emoticon ":silly:" to ask such question, but I really don't know why it's not running correctly, anyhow the sysctl values from the latest thunderbolt seem so unrealistic?:
Code:
vm.dirty_expire_centisecs = 3000
vm.dirty_writeback_centisecs = 500
But ok that's the thunderbolt settings, also I'm not sure if this really improves the system, I've noticed that the first few benchmarks score pretty high but then suddenly the sdcard read/write speed gets screwed by something.
Anyway, here are the scripts (so far):

[TWEAKS][SCRIPTS] Collection build.prop and init.d tweaks. Now with tweaks combo

Original Thread: http://forum.xda-developers.com/showthread.php?t=1709836
I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might be different from device to device, I've found these pretty consistent throughout many.
I didn't tested all of them, and i don't assume any risk!!! Use them at you own risk!!!
Some useful tips on how to use them at the end of the post

1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. vm management tweaks
Code:

echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure

5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
http://forum.xda-developers.com/showthread.php?t=860586
13. Loopy Smoothness tweak
Code:
http://forum.xda-developers.com/show....php?t=1137554
http://forum.xda-developers.com/show....php?t=1205744
14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
16. OOM groupings and priorities tweaks - SuperCharger
Code:
http://forum.xda-developers.com/showthread.php?t=991276
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
sysctl_tweaks and sysctl.conf tweaks
added by krabappel2548 Thank him
To make them work:
1. make a new file in /system/etc/init.d, name it sysctl_tweaks
2. make a new file in /system/etc, name it sysctl.conf
3. Paste the right code in the right file
1. sysctl_tweaks
Code:
#!/system/bin/sh
# grep sysctl /etc/init.d/*
/etc/init.d/02vm:# Load /sys/etc/sysctl.conf
/etc/init.d/02vm:sysctl -p
2. sysctl.conf

Is this work for Arc S with custom ROM,,,??? coz I saw the "htc" word on 3G tweak script
Sent from my LT18 using xda premium

it would be helpfull know which improove and which deprove specific Rom.
Im using JS 6.1 and for example i dont know if for example this random row:
- wifi.supplicant_scan_interval=180
could improove this rom or it has some better settings somehow

Actually htcmaskw1 command sets the perbit mask tranfer means that when u r on ur data conncetion in no wifi u get the max speed by the value
so the most optimized value has to be said there

I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might be different from device to device, I've found these pretty consistent throughout many.
I didn't tested all of them, and i don't assume any risk!!! Use them at you own risk!!!

Init.d
(needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)
1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
http://forum.xda-developers.com/showthread.php?t=860586
13. Loopy Smoothness tweak
Code:
http://forum.xda-developers.com/show....php?t=1137554
http://forum.xda-developers.com/show....php?t=1205744
14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
16. OOM groupings and priorities tweaks - SuperCharger
Code:
http://forum.xda-developers.com/showthread.php?t=991276
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
sysctl_tweaks and sysctl.conf tweaks
added by krabappel2548 Thank him
To make them work:
1. make a new file in /system/etc/init.d, name it sysctl_tweaks
2. make a new file in /system/etc, name it sysctl.conf
3. Paste the right code in the right file
1. sysctl_tweaks
Code:
#!/system/bin/sh
# grep sysctl /etc/init.d/*
/etc/init.d/02vm:# Load /sys/etc/sysctl.conf
/etc/init.d/02vm:sysctl -p
2. sysctl.conf

Turn Off LTE on Boot Init.d Script
On my LG Optimus G, even though I can select "GSM / WCDMA preferred" to disable LTE after a reboot it defaults back to "GSM / WCDMA / LTE".
I don't live anywhere near LTE and would like to have LTE turned off after powering up my phone. Is there anyway to create an init'd script for that?
I have done so much research and came up empty. This is actually a greatly wanted feature in the LGOG forums. Any help would be greatly appreciated. Thanks.

Thank you very Much! Very Awesome!

new performance tweaks!

I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might be different from device to device, I've found these pretty consistent throughout many.
I didn't tested all of them, and i don't assume any risk!!! Use them at you own risk!!!
Some useful tips on how to use them at the end of the post
This thread will be updated when new/better things come out

Init.d
(needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)
1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
http://forum.xda-developers.com/showthread.php?t=860586
13. Loopy Smoothness tweak
Code:
http://forum.xda-developers.com/show....php?t=1137554
http://forum.xda-developers.com/show....php?t=1205744
14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
16. OOM groupings and priorities tweaks - SuperCharger
Code:
http://forum.xda-developers.com/showthread.php?t=991276
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
sysctl_tweaks and sysctl.conf tweaks
added by krabappel2548 Thank him
To make them work:
1. make a new file in /system/etc/init.d, name it sysctl_tweaks
2. make a new file in /system/etc, name it sysctl.conf
3. Paste the right code in the right file
1. sysctl_tweaks
Code:
#!/system/bin/sh
# grep sysctl /etc/init.d/*
/etc/init.d/02vm:# Load /sys/etc/sysctl.conf
/etc/init.d/02vm:sysctl -p
2. sysctl.conf
Code:

I wish someone could turn this into a flashable zip. I'm a noob so it would be great!

great collections of script..
but on newer kitkat some of this script is not found?

[Q] Help with script.. script manager..

Hi..
I've run into a strange problem in script manager..
I'm trying to run the following
Code:
#!/system/bin/sh
# Sqlite Database Tweaks
#for i in `busybox find /d* -iname "*.db"`; do
# sqlite3 $i 'VACUUM;';
# sqlite3 $i 'REINDEX;';
#done
# Enable Write ahead Journaling mode
if [ -f /data/system/packages.xml ];
then
for i in `busybox find /data -iname "*.db"`; do
/system/xbin/sqlite3 $i 'PRAGMA journal_mode = WAL;';
done;
else
echo "May Need To Reboot after first boot for WAL to take effect";
fi;
but get a syntax error at "do"..
my ROM is CMX and busybox sterickson..
the first part (vacuum, reindex) I've commented it out but gives also the same error..
