Well virus-checking is pretty CPU-intensive(but not as cpu-intensive as
SpamAssassin!), and according to our internal tests all of our Sun's
(some Fire V120, som E450 and E220 and so on) have been dramatically
outperformed by our Intel Xeon 2,0Ghz Maschines with such tasks.
I do think that for such a task Intel-based system are far more better
suited than Sun - Systems due to there incredible CPU-frequencies(and no
- I don't think you need 4GB of RAM just for Virusscanning).
