ok.. im a noob at this... bt what is SWAP partition??? how does its size effect the performance??
It's a partition on your device that the system use when the RAM is full.
so if its grater in size.... that means its good... right??
and if so.. then y do devs prefer to keep it as 0mb??
Beceause it's easier to maintain it i suppose ^^
Its because there is no need for swap and it can reduce the life of your sd card, according to most ppl

But remember, swap partition will never be fast like device ram chip.
And if u want to achieve good performance witch swap partition, buy microsd card class 6 (not 4)
good luck
Or use the stock class 2 card

ok... how do i check the class of by card?? coz here in India they dont provide class info along eith the card... also there is nothing written on it.... my card gives me a decent transfer rate of 4-5 mbps while copying to the card...
Class 4, it give me 10mb writing speed
Sent from my HTC Wildfire using XDA App
then i'd say mine is class 2(4-5 mbps while copying pc to sd, where as 9-10 mbps while copying 4m sd to pc)??? any software that could assure me??
interesting I have 8GB sd card class 4 and writing speed is 2mb max... is anything wrong? ****

Either u have been fooled, or its a problem with ur Pc(coz my class2 card gives me 4MBPS),
or the number of files is too large
Example :- 1 file of 100MB will copy faster than 100 files of 1MB each...
getting my point??
Does it help more if I buy a new faster SD card (default card is a Class 2 card), or do optimizations such as this one: http://forum.xda-developers.com/showthread.php?t=888379
I'll probably get a Class 6 card, as I haven't seen any Class 10 yet for micro SD.

Yes, faster SD cards do help quite a bit. I used a class 4 for a while and it was noticeably improved for apps2sd on eclair. I got a class 10 for Christmas and the improvement over class 4 was definitely noticeable but not as dramatic. I've read that there isn't much of an improvement between class 6 and class 10 due to hardware limitations inside the phone. For HD video recording I've seen recommendations for class 6+.
Khalpower's optimization script is amazing for eclair. I recommend the JIT, optimized build.prop, overclock and apps2sd. There is also a newer JIT, but I'm not sure if khal incorporated it into his script yet. I think we're still struggling to get the froyo builds to measure up to the optimized eclairs.
Not sure though, I find my XT720 is more compatible with class2 SD cards. I've got one 4GB Class2 Card, one 8GB class2 Card and one 8GB Class6 card which all made by SansDisk. all of these, the most compatible one is the 4GB class2 Card. Although the Class6 card is faster and perform better, there's an issue with stability, where the phone frequently cannot mount the card when the phone is booted.
pls tell your suggestions.

there are class 10 micro SD but the prices are outrageous at the moment.
class 6 16GB is the best bang for the buck right now
the 32GB are still stuck on class 4
looking forward to get some 32GB class 6 when they come out
Thanks for the comments. I think I'll get a 16GB class 6.
32GB microSD are also still pretty expensive (above $100).
Been using the Class 6 for a day now and I can feel speed improvements in loading apps or data from the sd card. I also cleared the factory settings to start fresh.
I've got a class 10 16 GB microSD card for 30 € in Germany, which is about 40 $. I think that's a fair price. I haven't used it yet, so I can't tell you if it is faster or not.

the price cost doesn't match the quality...
it might be an imitation all original class 10 minimum price are over $100+ specially for the 16GB version
seems like they sold you a Class 4 16GB instead
run some test on it, and you'll find out

I'm always hessitant to buy something with that odd of a price/speed ratio. I was actually reading the reviews and found something VERY interesting. There was one person who was mentioning an app called SD Speed Boost that was described as being able to adjust the sd card cache, thus speeding up the read/write speed to the card. It was only a dollar, so I tried it.
WOW...
It has improved the speed of my system 10x. I was skeptical at first, but I realized that if I run SD Tools from the market to test the speed before and after, it shows a significant increase in read/write speed. Obviously, those of us who have apps and cache on our sd card are constantly hitting it and the card's performance will affect performance.
Does anyone else want to tackle this $1 app and confirm my findings? If this is the answer to our slowness problems, maybe the settings that this app changes can somehow be added to our ROMs for everyone to benefit!

Is this the app your'e referring to? My write speed stayed about the same @10.7MB/s but the read speed went from @16 to 23 with a 1MB cache. I don't have any apps on the sd card to verify that aspect of any performance boost but Media Gallery loaded pretty quick.
:Edit: A 2MB cache improved the read speed to 43MB/s

Yes, this is the app i'm using. I've been "field testing" this all day, and I must say that I have never had this type of responsiveness and speed from this phone EVER. I am loving this $1 addition to my phone. I have a class 4 card that seems to be giving me 6mb write/33mb read and that is substantially better. I've tinkered with the different settings and found arount 3000 giving me the best numbers with my specific card. I can only imagine that a different class card would need different settings.

Just installed.
OS: Dexter's 1.3 froyo with bugfix 2
SD Card: Adata 16GB Class 6
Speed Test
Average result from running 3x:
128KB cache: Read: 13.96MBps; Write: 6.63MBps
1024KB cache: Read: 22.40MBps (60% faster); Write: 6.93MBps
2048KB cache: Read: 36.67MBps (163% faster); Write: 6.90MBps
4096KB cache: Read: 33.67MBps (141% faster); Write: 6.90MBps
Interesting. The app seems to increase Read-speed only. I need to find an ideal cache size for optimal speed increase, so far it seems to be 2MB for me.
I'll rerun with my old Class 2 microSD card when I get home.

I think the app is just changing the value in /sys/devices/virtual/bdi/179:0/read_ahead_kb
The default value seems to be 128. You can set the value using e.g.
Code:
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
I have a 16GB Kingston "class 10" (see also complaints about this card throughout XDA--I got it as a gift and I believe it was on sale for $40 at the time).
I've been testing read and write speeds with "SD tools" (free). SD tools writes and reads 190 MB and displays a dial as it goes so I can see that the initial write speed starts pretty high (10 MB/s) and then quickly falls significantly within a few seconds (probably after an on SD card buffer gets filled) eventually stabilizing at 3.3 MB/s. So, clearly this card is not really class 10 at all as it cannot sustain 10 MB/s except for what seems to be a 1 sec burst. As far as read and read_ahead_kb goes:
128 -- 14.1 MB/s read (avg of 3)
1024 -- 22.4 MB/s read (avg of 3)
2048 -- 43.2 MB/s read (avg of 3)
4096 -- 38.2 MB/s read (avg of 3)
Optimal also seems to be 2MB for me.

Hi all, I have a couple of questions before I get my new sd-card.
1. I got my eyes on the SanDisk Ultra UHS-1 8gb class 10 sdcard with a write speed of 30mb/s(advertised). I was just wondering if there would be a noticeable speed difference (i.e. App loading time) if I partitioned that sdcard, as compared to my current class 4 Kingston sdcard.
2. Also, I've read from many forums that some devices don't see noticeable increase in speed from class 6 onwards... Is that true for our device too? (SGM)
3. Is ext4 partition better or ext3 partition better?

1. Well u surely won't get the advertised mb/s, but it will be a reasonably fast speed, as speed depends on your cable too (for trasnfer). I'm not sure, but yes u will notice that apps load faster (im basing this on what michie said in the swapping section of the performance thread, so its probably the same for loading from external partition)
2. Yes probably little difference between a class 6, 8 and 10. Maybe because most devices can't read beyond a certain speed or even if they do, that threshold speed is enough and lies in the range of class 6 upwards.
3. I don't really know, but i would suggest ext 4 as i see it recommended in many app to sd apps. Someone could clarify this.

Try Sd tools free on playstore to test your sd speed write/read before partition
(I try Speed Write true normal like sd class : 10Mb/s (class 10)
and test again after partition.
(I Test it & The Result Sd speed write reduce to 8Mb/s after partition but sd read Increase, test on my sd class 10)
If you want to boost more speed you can try free app called sd booster on playstore.
Good app to gain more speed.

So buying a class10 sdcard does help increase the apploading speed in a2sd?
Maybe yes maybe no? some sd different so you must try in my case. yes the speed reduce.
From 10 to 8Mb/s
but Read Speed Increase from 23Mb/s to 28Mb/s
if I use sd booster and set it on 6Mb. my sd write reduce to 6.8 mb but Read speed increase to 32,1 Mb/s
and I got more speed read to gain more smooth performance to play game and more.
also speed up booting on your phone.
but decrease performace make a file like recording and take a photo.
but speed app is awesome.

You didn't get my point. I'm talking about app-reading speeds in app2sd in an ext4 partition. As in app-loading time. Would it decrease?
Yes off course Increase If you boost your memory... more speed you have but low write.
I'm use ext4 partition too as my Internal memory with Internal HACK memory and OC.
Take a look.
Iam using sd class 10 transcend 16GB.
and use ext partition as default memory and now all of my app in ext4.
app speed & booting is great after I use sd class 10 then my old sd card sandisk 4GB class 4.

So the app-loading speed does increase huh... Alrighty then I'll consider getting a new one. Thanks much.
For a while no i've noticed my SD card getting slower when i transfer files.It's also picked up by antutu as well.It's a class 6 8gb Transcend.I don't use Swap or anything like that since i don't feel it neccesary for my needs.
Scores in antiutu went from SD read (110ish) to 30ish.Its performance has come down to that of a class 2.
Should i format it?What method should i use?
Any other suggestions?

dont take antutu's score very seriously because they are just BENCHMARK they are just tool to know the average performance . performance still depends on how you use it. but you can try reflash rom/ wipe sd using pc or reinstall antutu

I don't take antutu seriously,especially since i get about hte same scores with both top GInger Bread ROMs.But there's a huge difference in performance.
Obviously i should format it but which way is better?Through PC or the phone itself?
PS:FFFFFF i have to find 8gb of free memory D:
Have anyone seen the AnTuTu benchmark scores of the Samsung S5830?? ( I know it doesnt mean much, but where smoke is must be a fire)
Ok, so if I but my Ace's clock speed to 612MHz,my speed on the SD(read and write) is abought twice as fast as when I put the max clock on 883MHz.
How does this make sense??
Trancend 8GB class 10
May be... But what's the point ? Does it really matter why you get that speed as long as you get it ?

A weird thing. If you don't uc, you can't get a greater read speed and can't play heavier games if you uc. No answers in my mind ! Try a different SD card.
One more thing, don't go much on these benchmark softwares. They gave me wrong results. It showed a good speed for my sd when the actual write speed was merely 34kbps !

perhaps high frequencies you setted are getting crazy your device's processor

Any new way to increase SD speed except the read ahead value that google does not find? An using a class 10 card
