Dario, you have some fairly serious server hardware there, but
"harddisk of X GB, Serial ATA" doesn't mean much of anything. What
type of disks exactly, and most importantly, what RAID controller, and
what RAID level (1, 5, 10), and partitioned in what way?
More importantly, such a horribly awful slowdown (10 s page serve
time) with just two concurrent users is pretty strange.
That's not some disk IO limit due to e.g. RAID 5 vs. RAID 10 either
(not with only 2 concurrent users!), it's got to be something that
effects low-end performance too, aka, a mis-configuration problem.
I bet your AOLserver thread settings are wrong, that's probably
the easiest single way to make your performance really suck. See my
previous post and link above about that.
