The servers I've been testing are Intel E4500s with 2 GB of RAM and
Intel gigabit NICs, they are only on 100 mbit ports however and are
routed to through Cisco IP SLA.
The test client is on an entirely separate subnet and is an 8 core
opteron box with an Intel NIC however I've also run queryperf from
multiple sources at once using virtual machines.
The actual queries in my data file are captured from real DNS traffic
in our data center, about 50% of the queries end up hitting the cache.
I can see caching effects in my graphs as well.
