        Oh yeah! Wow, those sound great!

	That's exactly what a Bugzilla web head is--CPU/memory intensive 
without much I/O. Of course, if the DB goes onto a separate server, 
there should ideally be a 1GB connection between the machines or 
better--I assume that's the case between vbox and drawable?

	I suspect that performance-wise, it'd be best to just have a single 
enormous db.gnome.org. I've yet to see high-end database performance out 
of a VM, and high-end performance is ideally what we'd like to see for 
Bugzilla (not because it does thousands of operations per second, but 
because Bugzilla's Search functionality is very intensive). An ideal 
situation is for there to be two database servers--one master and one 
slave (both for backup reasons and for performance reasons--Bugzilla can 
do read-intensive operations on the slave), but again, I think the 
performance penalty of having them in a VM might outweigh the advantage 
of having two separate machines.

	I'll see if I can get Mozilla's MySQL configuration that they use for 
their current Bugzilla servers, for that last bit.
