[G2 and Desire Z Q&A, Help & Troubleshooting] KCRic:
Both of those methods do the exact same thing - one just takes no memory to do. All they do it set the read ahead buffer to a higher limit. Next time you open something from the sdcard - odds are it's still in the memory so it loads from there without needing to wait for the sdcard. It *should* work for a2ext also so if you have a slow card (or even a fast one) things will become faster. Not sure if it helps with linux swap though (not that we really need it) - will some one with swap test this to confirm?
[G2 and Desire Z Q&A, Help & Troubleshooting] Tommebaas:
Okay I installed SD tools and this is what came out:

before.

write speed: 7.7 mb/s

read speed: 17.5 mb/s

after.

write speed: 8.8 mb/s

read speed: 17.5 mb/s

So only the write speed improved...

u can try manually apply it.

/sys/devices/virtual/bdi/17:1/read_ahead_kb

change the value inside the read_ahead to 2048 or 3072

the italic, im nt sure its 17:1 or 17, something bout 17 im sure. inside got the read ahead

tis method however, change back to default after reboot
[XPERIA X10 Themes and Apps] GuestD2789:
I tried the hack. Changed cache size from 128 to 2048. Write speeds stayed the same, but read speeds went up by about 5Mb/s. My SD card is crap tho, only a class 2. I also only tried the one cache size.
[XPERIA X10 Themes and Apps] kr3g3r:

[XPERIA X10 Themes and Apps] chiefy009:
Using the app i can set at boot
[XPERIA X10 Themes and Apps] Eisel89:
there is no init.d on stock x10, so i set the file "99sdcardreadfix" to "run as root" and "run at boot" with "script manager" (free available at market).

The code working for me:

#!/system/xbin/sh
if [ -e /sys/devices/virtual/bdi/179:0/read_ahead_kb ]
then
/system/xbin/echo "[COLOR="Red"]3072[/COLOR]" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
fi

3072 was working best for me with the stock sd card.

read: 3,8

write: 73,4

If another value works better with your sd card, just change the red number to what you need

for 2.2 roms, you need to edit the script because echo is in bin, not xbin

download and use scriptmanager from the market, it will allow the script to run at boot.

works great on my 2.1 and 2.2 roms.

devs are not including this in their roms and no scripts are needed.
[XPERIA X10 Themes and Apps] Bialynia:
Thanks! That really did the trick for me, I am set at 1024 now, read speeds went up slightly between 6-7 mb/s while read speeds are around 25mb/s. I could get higher read speeds at higher cache but my write speeds would go down :(
[XPERIA X10 Themes and Apps] kradovan:
thread carefully

Hi

I just wanted to point out that read ahead buffer is not a real SD card performance booster. It is the way how your OS handles card reading and buffering data. I agree that illusion of speedup is present and large data set can really benefit from big read ahead buffer (like video audio and some others).

If you try other SD speed test applications like "Sst" aka "SD Card Speed Test" changing read ahead buffer will not make a dent because software is not using buffers to test real performance.

In some cases big buffer can really degrade performance because OS is cashing something that was not needed.

So my advice is to thread carefully and make read ahead buffer bigger only if you suffer from dropped frames in video or audio players, games and if you use app2sd.

Real performance boost can only obtained with better SD card driver if possible (custom kernel) and better SD card class 6 if possible. (not all SD card's regardless of class will not work in your device as expected eg. Kingston SanDisc Apacer and others research before you buy)

Kradovan :)

[XPERIA X10 Themes and Apps] BrunoPGomes:
I'm happy to root to make amendments like this, however for safety I always revert back to unrooted state before running normally. This gives me a little more protection from the malware currently making its way to us all.

Reading your solution, I'm sure it works, but would it work for a phone thats been unrooted afterwards? I have 2.1 with JIT2 and other speed tweaks applied.
[XPERIA X10 Themes and Apps] Eugene1991:
Weird the app SD Card Speed Booster couldn't install on my phone.. Maybe because of the ROM?
[XPERIA X10 Themes and Apps] chiefy009:
has to be 2.2 i think
[XPERIA X10 Themes and Apps] Eisel89:
Think it should work afterwards also. Becouse if you unroot the phone you simply can't access the system files any more, but i don't think it will disable all your changes an your system.

but its only my guess ;)
[XPERIA X10 Themes and Apps] XteNce:
it won't work. actually. guaranted.

phone owner won't have access to the sys files, but the system had, has and will have the access.

because we need to set it on every boot, we need to have root for our apps or hands which will set the number that we want.

think logically. no more
[XPERIA X10 Themes and Apps] kradovan:
I just tried to point out that it is not real SD card performance boost. Read ahead is OS feature how OS handles data.

Yes some applications will benefit from big read ahead buffers and they'll load faster and so on but you have to keep in mind that those buffers are created in RAM and you are reducing memory in which applications are executed.

And to conclude i like performance boost but it would be more interesting if SD card driver was one doing a boost.(or just keeping read and write speeds in constant)

Question:

Does X10 standard kernel supports EXT2 EXT3 or EXT4 file system and if yes what's the verdict regarding speed.

Kradovan :)
[XPERIA X10 Themes and Apps] kumayam:
I have froyo and it worked for me. If u have a task manager, make sure u ignore the app and second set it at boot. Good luck

[XPERIA X10 Themes and Apps] svtfmook:
sd card booster app only works on 2.2+ devices.

there's also reports of it cause lag in other apps.

imo, the script is the best way to go.

for those that want to use the script, but not use script manager. the script can be copied into a script that's already called at boot.
[XPERIA X10 Themes and Apps] XteNce:
yes, it does, (except EXT4 if I'm not wrong about this one)

if u know, working app2sd appeared since 1.6 on x10, and if it would start from 1.1 or 1.5 it would support it too. it's so because android is a linux based os and linux support EXT's for a rather long time (much longer, than the existence of android os)

but here's another question: can it possible to change sd card drivers on the phone to make the main sd card partition with EXT file system working like a usual storage we use on FAT32 file system?
[XPERIA X10 Themes and Apps] BrunoPGomes:
OK. You confirmed my suspicions - and thats how it happened in practice anyway. So it seems that the system has the capacity to override that setting back to 128 when it boots. So if one wishes to use the phone in unrooted production mode after the mod, does this become a matter for waiting until the boot bypass can accommodate it, or has anybody identified a method which enables this change to be applied using a trick applied using xrecovery? I find it interesting that it can be applied using DVM

[Atrix 4G General] marlasinger:
I have an Atrix on AT&T. Which means there's a bootloader encryption, and the carrier prevents non-market apk installations, which I have resolved since my phone is rooted and I have changed the boot animation already.

In order to do these things, I found Ghost Commander that would let me chmod my system directories...which is fine, but I feel kind of gimped that I can't do it on terminal.

Basically, what I want to be able to do is remount /system as rw using terminal.

This method doesn't work on both terminal and emulator on my phone. I have done:

Terminal:

sudo su
cd [sdk directory]
./adb devices
./adb shell
su
mount -o remount,rw -t ext3 /dev/block/mmcblk0p12 /system

and this is where I get stuck because I just get an Invalid argument error.

Here is some info about my sytem -

Usage: mount [-r] [-w] [-o options] [-t type] device directory

/dev/block/mmcblk0p12 /system ext3 ro,noatime,nodiratime, data=ordered 0 0

Been searching for the answers for a while now, and now I'm here. What am I doing wrong? Thanks :)

Run mount with no parameters and look for the line with that device name, should see rw in that line instead of ro.

I have a PPTP VPN setup to allow me to connect my xoom to home in order to use UPnP to stream videos and after about 5 minutes or a certain amount of data is transfered across the VPN, it goes offline. According to the Android system, it is connected, but I can't actually ping anything. If I disconnect the VPN and then re-connect it, it will work again.

Sounds alot like a setting on the router. I know some will limit the amount of data that can be Xfer'd through. A good test would be to use another computer away from home. try to do the same thing you are doing on your xoom. If the connection goes nuts then you know its not your xoom.
