I've got several customer with High-End machines like HP380. I configured them
with HT and installed Gentoo with FB-Classic. Then it's just a matter of page
size <-> buffers / ram to tweak the performance. 80-100 Users on a heavily used
20 Gig database is no problem. Best is: a complex statement can just "block" one
of virtual four cpus!
