How are you measuring the performance?
I'm looking at some links usage... I know that you could argue that this is
not consistent but these links have a very constant usage and today, after
the change they have a utilization that is 20% lower than usual.
My big doubt is why the new machine (that is A LOT better than the old)
spend more than 50% off cpu time on interrupts when the old just arrived on
60% at "rush-time"
The new machine is a Dell PowerEdge 1800 have one quad DLink DFE-580TX,

What else is the machine doing, firewall, nat, traffic
shaping, proxy?
PF+NAT+Squid+Qmail+Clamav+zebedee for 4 networks and about 600 users total.
