Sounds like the FreeBSD ports build cluster. :)

Kris, have you tried a PGO build of Python with your specific usage? I
cannot guarantee it will significantly speed things up though.

Also, a while ago I did tests with various GCC compilers and their effect on
Python running time as well as Intel's cc. Intel won on (nearly) all
accounts, meaning it was faster overall.
