Which kernel config did you use for the FreeBSD results?  In tests
that have been run on p4 hardware, the FreeBSD system's graph looks
more like NetBSD's than the one presented here.  FreeBSD's kernel has
a lot of debugging options that hurt performance on by default.  Also,
FreeBSD's malloc defaults to 'AJ' in head, which would result in
reduced performance.
