I've got an underpowered netbook that needs all the help it can get. I build in the VM with... -O2 -march=bonnell -mfpmath=sse -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables Even older desktops benefit. One case in point is my former Dell D530 Core2 Duo. When Gentoo had been installed, it could not keep up with the slowest stream of NHL Gamecenter Live. Everything was generic x86 with SSE2 thrown in, from the stage3. After re-emerging system and world optimized for the machine's cpu, it could keep up with not only the lowest quality stream, but a medium-quality stream. So yes, it helps. From http://gentoo-en.vfose.ru/wiki/Safe_Cflags#-march.3Dnative to find out exactly what your cpu is, run the following command on the *TARGET* machine... gcc -march=native -E -v - </dev/null 2>&1 | grep cc1 Ignore the flag output, which may be over-optimistic. Just look at what it says for "-march=". -- Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
