As far as I know, it is unsafe to use TSC on SMP systems.

I have actually made the changes to my.cnf before I ran these. I expanded
them quite a bit beyond what is in my-large.cnf. I need to pull them back
in to save on some memory usage. I'm going to look at some of the other

Yeah the static compiling recommendations by MySQL documents are really
more a linux thing more then anything else.
The other other thing to check is to make sure you use larger buffer
settings I recommend the large-my.cnf
cp /usr/local/share/mysql/my-large.cnf /var/db/mysql/
Then restart MySQL.

static compiling will link libpthread but not libthr.
Many thanks to all who responded. You are an incredibly smart group of
people.
The recompiling without static yielded much better results:
