Ah... Okay. That actually makes sense. Thanks for the clarification.

I would have thought, but some times it really gets slow and I'm trying 
to figure out why. When bogged down, the load averages are low. The main 
thing that looks out of whack is swap space, which seems to never go 
below 7%, but sometimes gets up into the 20%-30% range. When it gets 
that high, the server slows to a crawl.

last pid: 12732;  load averages:  0.44,  0.31, 0.27

187 processes: 2 running, 185 sleeping
CPU:  4.5% user,  0.0% nice,  1.1% system,  0.0% interrupt, 94.4% idle
