I'd just like to expand on that a bit... I was involved in getting the
theora-mmx branch to run on amd64.  So now MMX/SSE optimizations are
available on basically all x86-type processors.  This produces a
substantial speedup, by a factor of 2-3 in my experience.

The mmx branch has recently been merged into the trunk, so in the near
future you won't need to do anything special to get MMX-optimized
theora encoding working.  Hopefully Linux distros will pick up these
recent changes soon and package them up...
