Here at my work we are running a mysql 5.0 server on FreeBSD 5.4 using
the AMD Dual Core 64 chips.

current load is as follows:

Our queries per second avg has been going up consistently and we have
yet to have any problems. We haven't had any crashing though I can't
quite say how the thread level is comparing to yours.

I agree i would look into upgrading to 5.4-STABLE and see how that treats you.

As far as my experience the only real advantages I've found that linux
has over FreeBSD is the type of file systems. Some of the file systems
they support may give better performance to particular types of table
types, but that is more if you have a stable db server that is hitting
a bottle neck.
