Intel Core 2 Duo @ 2.4GHz.
Have you tried compiling it with gcc -O3 ?
Yes.
I would like to know, if there is a performance increase, when compiling ffmpeg with gcc -O3 instead of -O2.
Not for everything, AFAIK it's sometimes slower ???
Maybe some other applications, like the X-Server should also be compiled with -O3 to get a better performance with h264 decoding...
My xorg-server-1.5 is also compiled with icc :-)
