What will change??? > Sorry for my previous mail. In this thread I saw at least twice suggestions to use -Os flags. Never use this flags for all your system. For example compilling of glibc with this flags results in unusable system. Another thought about boot speed. Try to use prelink. I know that Red Hat Linux has it by default. Also note. May be it's good to use both -mcpu and -marh. Sometimes march is striped away so if you set only march then you stay without any optimisations... Usage of -fPIC can break your system. Try to rebuild your system (I mean emerge -e world) with such flags: CFLAGS="-O2 -march=athlon-xp -fomit-frame-pointer -pipe -mcpu=athlon-xp" Then enable prelink and make your tests... -- [email protected] mailing list
