Is this system running an amd64 kernel, or an i386 kernel?  One thing I
noticed when comparing NetBSD and FreeBSD performance for a very diferent
workload recently was that NetBSD/amd64 is missing even the most recent
optimized i386 versions of some fairly basic stuff like memset, memcpy,
copyin/copyout, much less versions tuned for modern processors (e.g. for
set and copy SSE2 instructions can be used if you know they're present, as
we do know on amd64).  I suspect FreeBSD/amd64 is better about this.
