Tried it just for fun and it worksLinkFrom 5.0 Mflops to 5.9 Mflops on 0723 firmw.Push the files in the system folder and chmod 755 on dalvikvm, then add "dalvik.vm.execution-mode=int:jit" to build.prop.And then reboot

Forgot to mention, this can make your device a bit unstable. So backup you files and to revert back change int:jit to int:fast

newbie here, can you explain what you said above, but in "newbie" speak

[quote name='mingnon;25113]newbie here' date=' can you explain what you said above, but in "newbie" speak[/QUOTE']"just in time" attempts to convert the java code run on a virtual machine into native machine code such that it can be directly executed by the machine's CPU. IOW it skips a step, or level of indirection if you like.In theory it should give some very good speed increases, although as discovered above I don't think that the ARM platform gets much development time for "just in time".Here's a nice wikipedia page:http://en.wikipedia.org/wiki/Just-in-time_compilation

[quote name='mingnon;25113]newbie here' date=' can you explain what you said above, but in "newbie" speak[/QUOTE'] I'll try, the Just In Time(JIT) compiler is just another type of compiler. This is one of the key features in 2.2 but the 2.1 has a beta version of it.The performance was measured in Mega FLoatingpoint Operations Per Second hence MFLOPS and the increase is about 18%By using the adb interfaceFirst pull the build.propadb pull /system/build.prop build.propOpen the build.prop as a text file and insert "dalvik.vm.execution-mode=int:jit" in the end of the fileThen push backadb push dalvikvm /system/bin/adb push libdvm.so /system/lib/adb push libnativehelper.so /system/lib/adb shell chmod 755 /system/bin/dalvikvm adb push build.prop /system/adb rebootThis may make your device a little bit unstableGood enough?

okay i sort of get it, but im not a "tech person" thanks for the attempt to explain, am going to have a look at the wiki

Is Froyo dalvik VM set to use JIT by default in Android 2.2? Not sure if this would help media apps like yxflash or Rockplayer play MP4 or H.264 much smoother?

[email protected] got 12 MFLOPS on Froyo.

That makes two
