A stratum-1 server will of course have enough RAM to never swap, a good 
stratum-2 server ditto.

My S-2 servers also use burst mode against its primary inhouse S-1 
references, this handles the case where an ARP table entry have aged 
out, causing the first poll in a burst series to take significantly 
longer than the rest.
