JIT Enabled - Performance boost

[Mad-Dog]

Hi All,

For those that are java aware, JIT is basically a runtime compilation and management framework that is at least from my firmware V1 now fully enabled and running.

To enable on your scroll

Add the following line without any quotes.

dalvik.vm.execution-mode=int:jit

in /system/build.prop

Then reboot.

For the none techies, here's a nice quote from; http://www.taranfx.com/android-internal ... z1IrNW0FVJ

the time when Android 2.1 was getting ready for release, JIT was all in there ready for the showtime. But for some unknown reasons, it was disabled, just a switch away from 2x – 4x times performance boost. But question is why wasn’t it unveiled at that moment. I could be wrong, though was in good-enough shape, it seemed like more of a marketing strategy.

As for me; The scroll is now much snappier in some apps such as gallery and various games. In fact I'd go as far as saying it's now very useable above and beyond the usual little hacks and mods.

I had read about this before and did not think it would work with the scroll, but I have added the line to the file and it booted fine and does seem like there is some speed improvement, some more testing needed, but so far so good. Cheers for the information

AngryBirds Rio plays much faster now, although still some graphical glitches in game. Think next stop needs to be the mali chipset and the kernel modules thread that seems to be popping up here and there on various tablet forums. As the opengl version is 131 it should be capable so I'm presuming the libs pushed out with the scroll are the "evaluation" shipped stuff from arm. May need some tweaks.

on a tangent I'm hoping to get some time in with Gingerbread pretty soon as I've been mauling with a port for a few htc devices.

Aye - that would help - I will see what I can do - is a system.img and boot.img of any help?

[rammy]

just the system.img for starters
