LS,
I noticed that when I compile boinc, it is always around 4x slower on the CPU benchmarks then the version distributed by Tumbleweed. I do use '-O3 -funroll-loops -ffast-math' as specified on the boinc website.
Tumbleweed build seems to use CFLAGS="-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -ffat-lto-objects -g -g -W -pipe -fno-strict-aliasing -D_REENTRANT" So maybe trying with just "-O2" and no other "optimizations" might be worth trying. If this is as good as the TW version, then I'd try if "-O3" improves. -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
