[HTC EVO 3D] smokin1337:
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.

Hope that helps...

V1.1 has more tweaks, so i'll leave the original in case you dont want the extra ones the ones in code above is from v1.1

Post some results here...
