FreeBSD MySQL still WAY slower than Linux

I tested a MySQL install on a Dell 6600. It's specs were 8 GB ram, 12 x 73
15k rpm drives (Ultra320) on a RAID5, 4 Xeon MP w/ 2 meg of cache, HT
enabled so the OS saw 8 CPU's.
Every time, a stock linux install (SuSE, CentOS, and Fedora) were always
faster than FreeBSD stock, or custom kernel utilizing different options.
I never could fully benchmark it running on Linux; as I never got the server
to max out before my benchmarking machine maxed out.
If your using 4.x, add these to your config file
options MAXDSIZ="(256*1024*1024)"
options MAXSSIZ="(256*1024*1024)"
options DFLDSIZ="(256*1024*1024)"
I noticed a HUGE difference on FreeBSD with those added, but it still
doesn't crank up there with Linux.
Also, default linux install's do not make it use more ram. You still have
to copy one of the my-xxx.cnf files over to /etc/my.cnf or
/usr/local/etc/my.cnf
MySQL is developed on Linux, and ported to FreeBSD. That's the best
explanation you'll get probably.

Your posting a lot of configuration here except the most easily
important one for performance in MySQL, thats your my.cnf configuration file
You will more then double your performance if you just start off by copying
/usr/local/share/mysql/my-large.cnf
to
/var/db/mysql
MySQL out of the box setup to use a tiny amount of ram and it wouldn't
surprise me if a lot of Linux distributions have a much more high
performance my.cnf file since most distributions are aimed at people who
don't know what they are doing.
