[MOD]Sick Speed Tweaks~Get the most out of your ROM !!

---

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

What exactly does this script do? this is like giving me a pill and just telling me it will cure cancer with no explanation

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?

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.

Should be its all android system edits.

A dalvik of 72 is a terrible, terrible idea, man. (No offense, I'm sure you put a lot of work into this script)

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.

how to "check out the scripts and see what they do"?
directions say to just flash it

theres no written explanation of all the tweaks somewhere?
