Most of the Fedora RPMS are provided as i386. These can easily be recompiled as: rpmbuild --target i686 --rebuild package.src.rpm a. Is it worth it? In other words, is there really a performance gain in packages like - say - KDE? b. Assuming that I installed the RPM sources and built from the spec file, as long as I am at it, could I also benefit by changing some of the FLAGS? For example: CHOST="i686-pc-linux-gnu" CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"
