Trouble with this is that netserver would have to run as root to be able to bind to the ports; it does that dynamically, so binding at startup and dropping privileges won't work. Also it would mean that no other services could run on those ports. For your use case, my guess would also be differences in the server connection (or peering), though. I do believe dslreports will open connections to multiple servers; you could try running one of the rtt_fair Flent tests against multiple servers to see if you can push more data that way... -Toke
