Can you contrast this against an i686-optimised version of glibc? 
You're showing that memmove is eating about 4% of your boottime.  I'm
curious whether optimised libraries would appreciably save any of that
(once you account for cache-misses, pipelining, etc.)  I haven't seen
anything that shows that optimised libraries are a big win for anything
other that floating point operations, and the serious users of those
(like openssl) tend to provide their own optimised versions.

Tks,
Jeff Bailey
