Matt, Haproxy is my load balancer of choice. You can always run multiple copies of haproxy and use some type of dynamic dns with it. We do this in many cases. Haproxy scales well. I've seen a single node sustain multiple gigabits per second with almost no sweat. Thanks. Sean On Monda

If your jumping between 5-25% iowait, I'd add nodes. Also tuning pdflush will help with the jumpy iowait. Lucid by default uses up to 20% of your ram before flushing. So say you have 10gb of ram, your system could be trying to flush 2gb of data causing huge iowait spikes. Sean
