I installed Pete's BB v0.5 (ERE53) yesterday. Using the stock non-overclocked kernel, I am stunned at how much faster 2.1 is over 2.01. Anyway, I am curious about the JIT compiler and edited build.prop to enable it. I understand from reading either here or somewhere else that you don't have to push the three files (libnativehelper.so, etc.) as they already exist in BB. I did indeed find the three files. So how do I test to see if JIT is actually enabled and working? I ran Linpack a bunch of times before and after enabling. The highest I've see after enabling JIT is 4.667 mflops. It seems to consistently return 4.6xx mflops with occasional drops to 4.5xx or 4.4xx. Before enabling, it seemed to return mostly 4.5xx with an occasional 4.6xx. With such a small difference, I'm not convinced that JIT is actually enabled & working.
