Are the packets only lost on setup, or are you getting intermittent packet losses?
What size packets are you sending? We've done throughput testing using a PC switch and get 500Mbps+ even for small packet sizes (at 512byte packets and greater we start to approach line speeds). .martin On Aug 11, 2008, at 3:44 PM, kk yap wrote: > Hi Martin, > > The hosts and switches are in the same machine, while NOX is running > in a separate machine.
