I only tested OpenSSL, because i know of the extreme diffs between 32+64 bit. But in your article you stated that you used 64 bit for all. Then those values are extra low.

I would be very interested to know if the current applications (graphmagik ffmpeg, etc.) were compiled with the compiler in use at the time the kernel was created.
I understand, that Intel has an optimising C compiler that produces substantially faster code then does gcc. Since the bulk of installations are on Intel / AMD platforms, it would be interesting to have a comparison of the last kernel and one compiled with Intel's C compiler.
