Check the archives for the -current mailing list for November or
December.  Scott Long posted some tests he did with MySQL on FreeBSD
5.3 with LinuxThreads, libthr, libpthread (libkse), and libc_r.  Quite
interesting read.

There's also been some posts to NewsForge comparing MySQL performance
on FreeBSD 4.11 and 5.3, with Gentoo Linux (2.4 and 2.6 kernels),
OpenBSD 3.6, and NetBSD 2.0.  It's a two part series that covers what
he tested, how he tested, and the test results.

And there have been some other posts to either -current or -stable in
the past couple weeks with other MySQL comparisons.
