Is it for rom cooks or developers? I tried it out in 2 different roms and it slowed down the phone. After a restart it takes awhile for rooted apps to be given su permisson. (Verry annoying) Even simple things such as plugging my phone into a pc took about 15-20+ seconds longer for my internal and sd cards to show up. Anyway I am back to basic 2.2 now and everything is running great again.
