It would almost double the size of i386.rpms (These sse2 libs would > have to be part of i386.rpms) - Is it worth it? If it is worth to have the SSE/SSE2 versions at all (i.e. the gains are big enough), then yes, it is worth it. You certainly can't put binaries/libraries requiring SSE or even SSE2 without any fallback for earlier CPUs into neither i386.rpm nor i686.rpm. Jakub
