Benchmarks, suggestions and researchs for kernel optimization

Hello guys,
these days I have done several comparative benchmarks of what can be achieved, at least in terms of performance, applying the existing optimization options or particular compiler flags and also the main kernel memory allocators.

This, I hope, is only the beginning...
I'd like that this thread could become a place where developers, experienced or not, can share their benchmark results, knowledge, suggestions on possible improvements, patches, etc designed to improve performance and / or stability of the kernel.

Inside the next posts, you can find the conducted benchmark results.
To perform each occurrence of them, I made at least 3 test runs for each of the following tools:
- CF-Bench developed by XDA Developer Chainfire
- Antutu Benchmark

Thanks for your attention

PS. Sorry for my bad english...
