Thanks Min - additionally if I'm incorrect in my assumption that the poll look in my example code should perform better, or if there's a better way to do what I'm doing just let me know.
The example code polls only one socket (which isn't that useful, hah) but I wanted to keep the test case dirt simple. The actual thing I was working on has one socket that should receive data at a relatively high rate (say 50k to 100k msgs/s) , and one socket that receives data at a much lower rate (say 1 msg/s) (for heartbeating, command and control, etc).
