Well, the "march=barcelona" option might give you a few more percentage points, since the "amdfam10" is for the mainstream processors, not Opteron specific

Thanks Bruno. According to the gcc documentation, barcelona and fam10 seem to be equivalent: http://gcc.gnu.org/onlinedocs/gcc/i3...4-Options.html. Am I reading that wrong?

Good catch! I was hoping they wouldn't do the exact same optimizations
