i use suse 64bits since a couple of release and one thing i notice it's slower than the 32 bits and slower than other 64 bits distribution (fedora and mandrake)
don't know if you use tuning option when you build...
We do build with -O2. Such a speed difference is interesting and I would be interested in the cause,

minimum to be done: -march=x86-64 i think x86 64 bits have minimum sse2 -mfpmath=sse2 -msse2 -funroll-all-loops -fomit-frame-pointer -ffast-math could be nice if more optimization can be done --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
