Can anyone tell me how to change the command line passed to the kernel for the LG 2X?
It doesn't seem to be included in boot.img files like with other phones. I'd love to change mine to allocate less memory for the GPU and more for the GPU (I think I don't need 128MB for the GPU, a lot of Tegra devices have it set to 64MB).

Hello,
I recently purchase a T-Mobile MDA. I love the phone but, it seems that the processor is just plain slow. It takes seconds between application launches. I have hear that I may be able to send my phone to some one who can speed it up memorywise?
My question is is this a good idea and how much does it cost?
As well as is there a way I can get a program to remove what is taking up space in my phones memory, storage and memory?
I am also confused about what a ROM is? Is this something I should consider?
I would appreciate any help, thanks.
You can send the phone and pay for someone else to do the same thing you can do, there is no hardware upgrade only software/registary tweaks.
There are several things you can do to speed things up, they have been discussed here extensively I would suggest doing a search.
Thanks man. Appreciate it.
I think the best way is to overclock...
I tried overclocking but to tell you the truth the best performance gains came from removing software (Anti-Virus) and reg tweaking.
Upgrade to a stable latest ROM could be a big step-up in speed as well, among some other improvements
first, upgrade to the newest ROM version.
second, run Omapclock to overclock your Wizard to a maximum of 260MHz. (240MHz is preferred)
Are there any drawbacks to this omapclock and over clocking mechanism?
eg. loss of memory space/storage space?
reduced battery life + possibly instability depending on how far you go.
I think some big differences need to be explained about speed and responsivness.
Speed is how fast the thing actually runs, responsivness is more what it sounds like this guy wants.
In our case, speed will help us squeeze another 2-3 fps out of our video players, where responsivness will make a program load in 1 or less seconds. Your standard reg tweaks and hacks will help with responsivness. If you have a video file that is kinda skipping or laggy, then overclokcing will help.
You will get little to NO performance difference with a few mhz overclock on your main OS.... I would be suprised if it did anything and not surprised if it slowed down.
In the end, look about the forums, there are MANY hacks and tweaks here posted and on other websites off of google which will help with your responsivness problems.
Some search items to look for:
GDI, animated menus, fat or fat32, cache
Thats off the top of my head, those should make you run pretty fast.
Let's do better
Here goes :
Speedup Display :
[HKEY_LOCAL_MACHINE\System\GDI\GLYPHCACHE]
Limit=8192
Disable menuanimations :
[HKEY_LOCAL_MACHINE \SYSTEM\GWE\Menu]
AniType=0
Speedup filesystem:
[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\]
CacheSize=4096
EnableCache=1
I don't understand this post. How do I use these links?

they aren't links, they're registry changes
you'll need to find a registry editor to do them
Okay, I have a registry editor, as in memmaid, and resco explorer. Can someone explain how I perform these registry changes?
The are probably better and more detailed explanations but basically:
1) Launch the registry editor
2) Navigate the tree structure to the appropriate part (like using explorer for files)
Then either,
3) Edit the appropriate value (i.e. 'Anitype' is already a variable in \System\GWE\Menu) - select the variable (tap) then enter the corrected value (i.e. from above DWORD value is '6' change to '0')
or
4) Insert a new variable with the precisely correct spelling, then enter the appropriate value(s).
NOTE: You have to enter the correct type of variable, but generally you are adding:
Key (like a new folder)
String Value (has a name and then a 'string' value)
DWORD Value (has a name and 'DWORD' value, usually in dec not hex)
Hope that helps... like i said, there are better explanations out there...
PS you should often have to re-start your device for the changes to take place!

Open the Resco Registry Editor, search the key which is between the [] and adjust the values as suggested above.
Hi Guys,
Something that's been bothering me for a while now, hopefully someone can explain or investigate where I've failed to find the answer.
The registry key
HKLM\System\StorageManager\IMGFS\ShadowROM = 1
should cause ROM to be "shadowed", that is, copied to RAM and executed from there instead of the 32mb flash.
If that's the case, why is it that switching this key to 0 not free up 32mb of RAM, and setting it to 1 does not eat 32mb of ram? In fact I've seen no change in memory usage between the 2 settings.
I've tested this setting in TuMa 1.3 and Ivan 3.x and 4Rx. Is it possible that this setting does nothing in the version of IMGFS.dll used, or that this key is set to 0 in the smaller default registry and untouchable without re-cooking the ROM?
Or does IMGFS shadowing work differently to the way I've described it?
All executable files from IMGFS are decompressed to RAM and run from there. Nothing can be run directly from IMGFS (unlike was in older OS versions). I don't know the meaning of this key, and there are no noticeable differences when changing it.
Confirmed, this is a dead key. Even deleting it has no effect whatsoever on memory use or performance.
Hi just checked the pocket Hack master site no support for the Qualcomm MSM 7201A cpu..
any knows a tool that allow to define the speed that cpu should Run .
Thanks
There exists no tool to over- or underclock the Qualcomm cpus.
TDO
not for now
but maybe soon
yes, there is one, is called nueclock or nuedynamic clock
there is one, is called nueclock or nuedynamic clock
Run sh /system/bin/swap -s to check swap status and other mod values.
Ok so I did this to check on my stuff, cause i wanted to make a compcache.
*** CompCache ***
compcache_en=0
cc_memlimit=16
cc_disksize=32
cc_backingswap_en=0
cc_backingswap=/dev/block/mmcblk0p3
swappiness=30
*** Linux Swap ***
linux_swap_en=1
linux_swap_partition=/dev/block/mmcblk0p3
....................
=== Linux Swap status ===
Linux SWAP enabled on /dev/block/mmcblk0p3
Linux Swap: swappiness - 30(system) 30(user)
i'm running JACxHEROSkiv1.5r2 and want to know what I can do to inprove the speed of the ROM.
Any suggestions are welcome i'm not much of a programmer
Looks nlike you need to edit the"cc_disksize=32" value, but I doubt that affect the speed tbh.
What size swap partition are you running?
Im running with 96 MB linux swap
btw what is that (cc_disksize=32) ?? the linux swap size ?
I read i a couple of posts about the linux swap and compcache and read that if you enable comcache it could speed up your device slightly.

Ah thought CC was already enabled.
compcache_en=0 < This needs to be changed to one to enable CC.
cc_disksize=32 < That's the CC size, I wouldnt change it.
I would *strongly* recommend reducing your swap size. It seems to be that the bigger the size, the faster it is at first, but then the phone starts to get really slow. Go for 48 or 64mb.
I don't really know a lot about CC, I've never edited the config files for it as it's generally set up for optimum performance already (and I also don't like the idea of it wearing out the nand). If you look in the xHero there are other configurations for CC, CC+swap, swap, CC +backing swap that you may want to look at.

Alright. Ran a 96 mb swap all day to test. Load screen about equal. It was "ghost lag" where you do something and it freezes for a minute

Ok then i better change the size of my swap. also does it matter if your on ext3 or 4 ?
And what is the difference between linuxswap and compcache ?
Sorry for these noob questions but I'm a bit lost

no ext doesn't matter.
Compressing pages and keeping them in RAM virtually increases its capacity. This allows more applications to fit in given amount of memory.

The problem is the Hero UI is quite CPU intensive, so less CPU power can be devoted to compressing/decompressing files in RAM.
Linux-swap is a separate partition where files are paged, increasing the amount of memory. The difference being it's outside the RAM.
Hello there,
two days ago i flashed teamhacksung's ICS aka CM9.
Firstday: everything smooth and okay
Second day: launcher starts to FC here and there, in the cm9 thread i found this "guide" (to bad that i just copied it to an txt and didnt copied the link...)
Code:
1. download Rom Toolbox from market, install, open
2.change to performance tab
3.build.prop tweaks
4.VM heap size to 48 mb
5. program will ask to reboot do it, go to toolbox again and choose Auto Memory Manager
6.choose presets->default
7.reboot and/or wipe cache
i downloaded Rom Toolbox and checked heapsize, currently its 128MB. So my question, is step 4 meaning to increase heap size from somthing default (<48mb) to 48mb or is it meant to decrease from current 128 to 48 mb? if i'm not remembering wrong, i had to increase heap for my tomcat server after having problems. so, (if its meant to) why decrease heap in android from 128 to 48? a short explanation would be cool.
I hope someone can help me with the heapsize question, i dont really want to make it even worse
Thanks in advance
Maybe will help u:
VM Heap Size
The heap is an area of dynamic memory allocated to programs. With a larger heap size, there is more memory for the program and the garbage collector can run more efficiently. Therefore, it is possible to get better performance by setting a larger VM heap size.
However, if you set it too high, you can run out of free memory which can trigger swapping which will degrade performance. Therefore the VM setting is a trade-off.
The optimal value will depend on the RAM on the device as well as the programs and usage patterns, therefore the optimal setting can often only be determined by the user experimentally.
Default value: varies between devices

source: droidgram[dot]com
It should be noted that in the ICS builds the build.prop now contains 3 variables pertaining to the heap size:
Code:
dalvik.vm.heapgrowthlimit
dalvik.vm.heapsize
dalvik.vm.heapstartsize
With the size in the tweaker referring to dalvik.vm.heapsize, the other two are new.
I have no clue as to what any of this means but I thought I should mention it.
Thanks for this informations, i'll try a lower value than 128

damn...
it was way smoother (at least what i saw until now)...
but at least mp3 player (default music app) does not start...
first i set to 64m but as i saw that mp3 didnt work i thougt, maybe to less... i increased to 96 but here was mp3 also not working, after setting back to 128, still not working mp3...
as in the guide, i always cleared cache after changing value.
someone got an idea? do i have to reflash cm9?
