Hi, Aaron. I've noticed a difference between FC6/Centos5 and F10 in how 
'snappy' they feel, though I haven't compared them directly much. The 
only 'measure' I have is (don't laugh) Gnomine; if you hit a square that 
  opens a lot of squares, it's instant on FC6/Centos5, but it seems 
unintentionally(?) 'animated' on F10. This is presumably such a simple 
program that I guess the reason in this case is a much more complex 
graphics/GUI subsystem. (This is all on one system; dualboot).

I wonder how one could profile an entire OS to find out where the cycles 
   go? Is it feasible?

(Disclaimer: I used to have FC6 on the machine, but changed to Centos5 
some time after the FC6 lifetime. I'm not sure about how directly they 
would compare performancewise; am I wrong in thinking that they 
shouldn't be too far apart? )

Best regards,
