So looked around for something for me and I have found this

Code:

CFLAGS="-march=athlon-xp -mcpu=athlon-xp -pipe -O3
-fomit-frame-pointer -fstrength-reduce -frerun-cse-after-loop -frerun-loop-opt
-fexpensive-optimizations -fschedule-insns2 -mfpmath=sse -mmmx -msse
-m3dnow -momit-leaf-frame-pointer"

what do you thing about this?? isn't it to much agresive?? I really have no
idea what I'm trying. (firsttimer to linux :oops:

:oops:

)
Could somebody tell me what to use and what not or possibly change.
thx

Mickel
