What CPU do you have (MHz)?

Have you tried compiling it with gcc -O3 ?

I would like to know, if there is a performance increase, when compiling 
ffmpeg with gcc -O3 instead of -O2.

Maybe some other applications, like the X-Server should also be compiled 
  with -O3 to get a better performance with h264 decoding...
