Is there anyway that you could make the changes in an script, so we can apply them to other roms too (like MIUI)?
Thanks!
Mo.
P.s. I mean the once that you can obviously convert to an script (like noaccesstime and readahead)

Interesting! Who doesn't like "tweaks"!? Thanks

This should also work with any MIUI/CM7 ROM.
I dont use MIUI so I cant test it.
Make a Backup, flash the zip and test it. If it works, please report here, so i can update the post!
If its not working, restore your backup

Does it exist VoodooColor for i9100?

Not yet...but if you install a kernel, which supports voodoo color, you get a very nice colorprofile!

Thank you for this zip
I don't really see the reaseon to delete all these apps (except for the books app as this service is not available everywhere) so I'd love to know how to change this in your zip so I get the other tweaks but keep the apps.
What exactly does the VoodooColor stuff do?
Zipaligning on each boot? Is that really needed? I thought you'd do that once for all apks an then it's done and good...
Do the noatime, swapping, dritystate writeback and minfree tweaks have any drawbacks/problems?
I manually changed the DPI settings on my Desire once and some apps (like Frenzic) didn't like that too much...

VoodooColor -> see my last post
The zipaligning script checks if there are any NONzipaligned apps, if yes, they are zipaligned
No Problem here (so far)
Hm...i only decreased the dpi from 240 to 200 ... got no problems (so far ) I use this script for 2 weeks now

And what kernels support it?

I just tested on Miui. Its not fully working 100%. Status bar gets FC. The dpi works. But there are some misalignment

Erm, the only problem I have is the StatusBar and thats due to the density change. Could you please tell me what the original density is?
For everyone else, if you apply this tweak on your MIUI rom, it will "hide" the statusbar. You would need to change the density back to the original.
Edit: Never mind, found it. It is 233. Will post a link soon.

For MUI
Hello.
For MIUI users, I have *slightly* modified the zip file and have uploaded here:

All credits goes back to nexxx85 for all hard work.
Thansk,
Mo.

maybe is a dumb question but now which kernel uses voodoo color on cm for sgs2?

There's no modified CM7 kernel at the moment, so there's no kernel which supports voodoo color

---

Thanks for your replies regarding MIUI.
Ive uploaded a ZIP for MIUI with standard density (233). Thanks to mofirouz!
I will upload a version without APP REMOVAL later!
EDIT:
Seperated app removal to a flashable zip.

Hi,
I´ve made a flashable zip with some Tweaks for our beloved SGS2.
Tweaks:
CM7 only: Permanent changed DPI to 200 (not changeable with init.d script, because of ro.)
Added zipalign binary
Zipaligneing on each startup
Europe GPS Config
VoodooColor preparation (will be automatical applied, if VoodooColor Kernel is installed)
Dalvik Heapsize 70m
CFQ Scheduler (including tweaks for non rotating storeage)
All partitions mounted with noatime (no accesstime when reading...saves quite alot diskusage)
SDCard readahead 2048kb (SdCard speed inc. by 2-3x)
Disabled swapping
Increased dirtystate writeback times (less battery usage)
Optimized Memory Settings (minfree)
WIFI scanintervall 3min
Windowevents set to 60 (much smoother scrolling)
Cleanup sqlite3 Databases on each startup
Click to expand...
Click to collapse
isnt 64mb Dalvik Heapsize enough?
doesnt cm aready use cfq? what is rotating storeage?
why use noatime?relatime for system,sdcard and emmc is enough.data and chache already use noatime.
SDCard readahead 2048kb.high readahead always has drawbacks...for example increased disk i/o and ram usage...benchmarking with standard sd benches is pointless if u read from ram cause of readahead.it all depends on usage patterns.what is the standard readahead value?
Disabled swapping:did android ever swap? dont think so.
Windowevents set to 60 any drawbacks? higher cpu i/o and ram usage i guess.
Increased dirtystate writeback times (less battery usage)ls provide a figure.

64 vs 70: Why not give Dalvik a bit more room to work?
cfq is standard for CM7, but its set again to give all options needed for optimization... cfq is default optimized for rotating storage (like HDD) but sgs2 uses flash storage (no moving parts )
why use relatime..i dont need any accesstimes
sdcard readahead...we have enough ram+cpu power.. so why dont speed up the slow sdcard?
dunno if swap is enabled by default...gotta take a look later
windowevents 60: why dont enjoy smooth ui with all that power inside
higher writebacktimes means lower sdcard/cpu usage -> lower battery usage
This is my optinion for all the tweaks! If Iam wrong, please correct me

then use noop or deadline scheduler i would suggest.maybe access times are needed for some ppl or programms. theres a reason for relatime...
what is the default writeback and windowevents value?

@OP, you said you are using this for two weeks, please give your feedback on battery life...

Default windowevent value is 55
I never had any problems on any (of my 4) linux machines with noatime (but ill keep it in mind for android)
I think CFQ performance (optimized for ssd) == noop or deadline ( but ill take a look later)
