Let's check... Oh, it's a different machine it's the one I
use for:
http://www.suse.de/%7Eaj/SPEC/CINT/sandbox/index.html
But nevertheless the numbers look wrong...
I found it - I forgot to add -O3 :-(
Ok, I rerun the tests with correct flags now:
cflags base: -O3 -fomit-frame-pointer -march=athlon -funroll-loops -fstrict-aliasing -malign-double
cflags peak: -O3 -fomit-frame-pointer -march=athlon -funroll-loops -fstrict-aliasing -malign-double
Sorry - and thanks for looking closer into these...
Andreas
