The binaries shipped in x86-64 Linux distributions should be already pretty well optimized for K8. It's unlikely you can get much improvement
They're not... just look at my simple openssl comparisons: http://www.miguelito.org/openssl. The good news (for AMD and fans.. :) ) is that amd chips get a huge boost at recompile. Em64t gets only a little. My guess is the stuff was compiled with the most generic x86_64 support, much like many distros will build some things for i386 (or i586 mostly these days I guess) instead of optimized more.. in order to support the most people OOTB. -- Mike Marion-Unix SysAdmin/Staff Engineer-http://www.qualcomm.com A polar bear is a rectangular bear after a coordinate transform.
