This jives with my experience, too. The 3d ray-tracing feature is very
popular, and if you get several simultaneous hits (like from a class)
the server will slow down.

It's the support packages: pari/gp, MuPAD, GAP, maxima, povray, that
most of the time in my first installation. Georges could be a real help
there - I'd take advantage of the offer. Once you get it installed, it's
a breeze to upgrade and maintain.
