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...
