Dear Nick,
Can you post a set of e.g. netperf results? The thing that I'm most
interested in is a table of the raw bandwidth as a function of message
size in UDP_STREAMS and/or TCP_STREAMS (see the graph on
http://www.phy.duke.edu/brahma/ for an example) and perhaps a RR test to
give some idea of the latency.
Please indicate the kind of hosts being connected, as well -- I see a
significant difference in the small-packet numbers for faster hosts as
might well be expected, given that the small-packet traffic is often CPU
bound.
