And it's a very nice performance gain.  Percent spent waiting according
to "top" is down around 10-20% instead of 80-90%.  While I'm not
prepared to benchmark, database performance is way up.  The client
machines that are writing the data are running closer to 100% CPU
(before they were well below 50% CPU utilization).
