And on the various SSE-capable CPUs, how much benefit does that actually give us? I'm after a system-wide answer, not a microbenchmark for zlib or crypto code. It should take into account any overheads involved in saving/restoring registers on context switch that wouldn't otherwise have to be saved/restored. -- David Woodhouse Open Source Technology Centre David.Woodhouse@xxxxxxxxx Intel Corporation -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
