[x265] Recent Frames/second benchmarks per platform and per clip?

[Mario Rohkrämer]

Thanks, Tom.

Yes, I already did batch testing, even just on a small video (QCIF  
foreman); one with larger dimensions would be more accurate, but running  
it 3 times each (to avoid mistakes by random slowdown effects due to  
surprising activities, you know, it is Windows...) in the slowest presets  
will take several hours per 10 seconds, so my hardware is not suitable  
anymore. Nevertheless, I will stay curious, and I trust your efforts.

I already published a PDF with a few graphs here in this mailing list, I  
may do that again soonish with additional results of more recent builds.
