I've took machine and installed binary FreeBSD(amd64 8.2-p4 GENERIC) on it.
Then I've installed 'benchmarks/unixbench' port.
So everything is a default generic binary install ('make.conf' empty - no CPU
optimization flags)
After running: '# time unixbench', final score was:
394.2
Completed in 22.8 min
Then I've recompiled everything, from src, world and kernel, with 'make.conf':
--
CPUTYPE?=core2
CFLAGS+=-march=native
NO_CPU_CFLAGS=yes
COPTFLAGS+=-march=native
NO_CPU_COPTFLAGS=yes
--
After reboot, I've run: '# time unixbench', final score was:
313.5
Completed in 26.7 min
I'm getting worse result, with optimized FreeBSD's binaries?!?
How come?
