Hi Josh, thanks in advance
How many requests/sec are done? If these bots are running fast then
this might be fine depending on your application.
In this test, we got about 20 request/sec
How much of the CPU time is iowait? Try the tricks listed here
if you want better performance ( especially Loader() )...
We don't know, because top utility hasn't it. In other hand, with vmstat utility, we got about 305 blocks/second sent to a block device.

Also your CPUs are a little slow by current standards.
Check out http://chamas.com/bench/ from some old numbers
on execution speed for a certain system.

Josh
