	We need to know many things here:

	- CPU, RAM, disk, disk layout, swap

	What does disk I/O look like ? (gstat)
	What does network I/O look like ? (netstat -ain 1)
	Interrupts ? (vmstat -i)

	Have you read tuning(7) ?  There's a lot of info in there about
	socket tuning, network buffers, etc...

	Check out what the logs say, eventual warnings on the console, etc...
