My understanding is that it only makes sense for the kernel and glibc to be optimized - and that those already are. Since almost everything is linked against stuff in glibc, they benefit from that optimization - and that optimizing most other packages doesn't really make much (if any) performance difference. Back in the RH 6.2 days I built pgcc (pentium optimized gcc) and rebuilt every rpm using it (except for a few that refused to compile with pgcc) and I thought I would have a fast system. Reallity is - the performance boost was minimal. More performance could be gained by adding ram and/or swapping to a different disk than your data disk(s). > >If I understand the manual correctly I would have to download the >src.rpm then run the command rpm --rebuild xxx.src.rpm which would >install the software after optimising it for the i686 architecture. > >Or isn't it that simple? You would need to first create a ~/.rpmmacros file In it you want the following: %_topdir /home/your_user_name/rpmbuild %_build_arch i686 then - mkdir -p ~/rpmbuild/RPMS/i386 (same for i686 and noarch at a minimal) mkdir ~/rpmbuild/SPECS mkdir ~/rpmbuild/SOURCES mkdir ~/rpmbuild/BUILD Then (without su to root) rpmbuild --rebuild package.src.rpm I *think* it will deposit the rebuilt rpm into ~/rpmbuild/RPMS/i686 (I haven't tried) If that doesn't work - edit the spec file and add- BuildArch: i686 to the spec file. That *should* work. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
