Does NOT work with aosp roms, sorry...
This is what i use in my rom and it works great. I have tried these script with a few other roms and the work with them too.
They make the roms snappy and very fast. Also give a boost in quandrant scores.
Some roms adjust some of the settings in these scripts too but i havent had ant errors with any roms i have tried. Please post if you have any issues with anything.
Devs feel free to add to your roms just leave the #smokin1337 in the scripts if ya dont mind.
Lowered the dalvik heap, will add more later ...
Just flash the zip in recovery to install
EDIT:
v1.1
Since a few people won't use this without basic info here it is:
This script will work with any 2.3.4 rom and afaik aosp or sense but i don't use aosp so i can't say for sure.
The scripts include:
Kernel tweaks
VM tweaks (swappiness, minfree, adj, etc.)
Optimized mounts
Cache Cleanup
SDCard read ahead to 3072
Dalvik Heap to 32 soon to be 48
SQLite Vacuum
tcp tweaks
IO scheduler set to deadline
Chmod User Log Files that go to HTC
Setprop Tweaks are:
VM Props
GUI Tweaks
Video/Pic enhancements
Disable HTC Checkin Service
LCD Density
Disable debug icon
Increase WiFi scan interval to 120 sec.

If you open the zip and read the scripts you'd see.
It basically changes a bunch of settings on your phone, dalvik heap to 72mb for example, readahead speed increase on the sdcard, a bunch of other stuff.
This is safe for sense and aosp roms?
Sent from my PG06100 using Tapatalk
It's basically all the speed tweaks out and some i found doing some research. It changes quite a few things as the previous poster said check out the scripts and see what they do, which is good practice to do all the time. I edited the values for speed on my rom but it should work with any existing rom.

Whats a good setting ? Seemed ok to me i read some that said higher is better and some said lower is better. Neither seemed to make much difference so i left it high.

It'll be smooth for a while, but the problem with that is that it will take way too long for the garbage collector to come and clean up after the process. There's a better way of explaining it, unfortunately, I'm not sure how to.

Nah not really i looked them up on google, i adjusted them back and forth to see what helped and what didn't. I'm gonna lower the dalvik heap with the advice of liquid solstice to 32 just to be safe.

I would do 64M, gives everything enough room to breathe and it's sort of the 'standard', I guess. Amything more is no bueno as LS pointed out and anything less is limiting our phones. Just my thoughts.

@ dalvik tweaks
I see a lot of different settings people either go with 32 or 64. On my ROMS I run 48 and am happy with that. I may give 64 a go and see what it does.
@OP - Good job!

The best setting is about 48MB. If it is too big then it takes a long time for the garbage collector to do its thing and the cache can grow to really large levels after you have been running the phone for a while. 48 is a good balance because it allows more space to be used for apps, but isnt so large that the cache's grow crazy big.
Starting this thread to share experiences with any good sysctl settings for the flyer.
What is sysctl?
Sysctl is an interface for examining and dynamically changing parameters in the Linux operating systems.
What is sysctl.conf?
sysctl.conf is a simple file containing sysctl values to be read in and set by sysctl command. The syntax is simply as follows:
# comment
; comment
token = value
Note that blank lines are ignored, and whitespace before and after a token or value is ignored, although a value can contain whitespace within. Lines which begin with a # or ; are considered comments and ignored.
Where is sysctl.conf located?
sysctl.conf is located in /system/etc/ directory on your tablet.
Changing sysctl values
You could pull the file /system/etc/sysctl.conf from your phone, edit the data, push the modified file back to your phone.
However, it is easier (provided that you have init.d) to use a script in /system/etc/init.d/ which is ran at boot time to change the values:
Example via init.d script
You could have a file, e.g. /system/etc/init.d/84sysctl
#!/system/bin/sh
sysctl -w net.ipv4.tcp_fin_timeout=30
(this would change socket FIN timing)
Advantage of doing like this is that you don't have to modify your original /system/etc/sysctl.conf file.
So far I have been using:
sysctl -w vm.dirty_ratio=90
sysctl -w vm.dirty_background_ratio=55
sysctl -w vm.vfs_cache_pressure=10
sysctl -w vm.swappiness=0
sysctl -w vm.panic_on_oom=1
sysctl -w net.core.wmem_max=1048576
sysctl -w net.core.rmem_max=1048576
There are two import settings which control the kernel behaviour with regard to dirty pages in memory. They are:
vm.dirty_background_ratio
vm.dirty_ratio
The first of the two (vm.dirty_background_ratio) defines the percentage of memory that can become dirty before a background flushing of the pages to disk starts. Until this percentage is reached no pages are flushed to disk. However when the flushing starts, then it's done in the background without disrupting any of the running processes in the foreground.
Now the second of the two parameters (vm.dirty_ratio) defines the percentage of memory which can be occupied by dirty pages before a forced flush starts. If the percentage of dirty pages reaches this number, then all processes become synchronous, they are not allowed to continue until the io operation they have requested is actually performed and the data is on disk. In case of high performance I/O machines, this causes a problem as the data caching is cut away and all of the processes doing I/O (the important ones in dCache pool) become blocked to wait for io. This will cause a big number of hanging processes, which leads to high load, which leads to unstable system and crappy performance.
vm.swappiness=0
We don't swap ... so no need.
sysctl -w net.core.wmem_max=1048576
sysctl -w net.core.rmem_max=1048576
Increase the max size of TCP/IP send/receive buffers.
sysctl -w vm.panic_on_oom=1
This enables or disables panic on out-of-memory feature. If this is set to 1, the kernel panics when out-of-memory happens. If this is set to 0, the kernel will kill some rogue process, by calling oom_kill(). Usually, oom_killer can kill rogue processes and system will survive. If you want to panic the system rather than killing rogue processes, set this to 1.
vm.vfs_cache_pressure=10
This is more interesting. File system cache (dentry/inode) is really more important than the block cache above, so we really want the kernel to use up much of the RAM for them. The default value is 100, and what you want to do is lower that value to tell the kernel to favor the file system cache and not drop them aggressively.
i like!!! but how would you change a build.prop property? cause at first i thought sysctl was for changing build prop stuff =X
This is a known LINUX Speed Tweak, and i found it on the epic 4g thread that was started by marcusant. So, i'm really just sharing the info with the Xperian community, but I truly think it is quite valuable info, and will likely work on any Android based device since as stated earlier it is a Linux tweak. This has only been tested on ICS, and JB, but I'm pretty sure results will be the same with our XPERIAs...

AND Lotz More
to a file sysctl.conf (you can use root explorer to make a **NEW** file, or whatever file manager tool you like) then using root explorer copy the file and navigate to /system/etc/ mount as r/w and rename the original sysctl.conf file to sysctl.conf.bak, then paste the one you originally copied (you can add the lines of code to the original file if you are using a edited one already). Then change ownership to root/root, and permissions to rw/r/r, then mount back to r/o, and exit root explorer, and reboot. If it works you should notice your browser opening pages faster, the market much faster, and of course speed test will be faster.
This is highly unlikely, but if this somehow breaks your device I am in no way responsible...
