[netperf-talk] multithread support and other feature ideas

[Brandeburg, Jesse]

in these days of multicore systems, what is the state of multithreaded netperf?

also, one of the coolest features of the old ttcp was that it had a polynomial based traffic generator mode for detecting data corruption.

it was cool because the polynomial only repeated the same data pattern every 2^something huge bytes, which made it easy to predict the value of any given byte at the other end, and made detecting single byte data corruption simple.

I'm not sure if the polynomial thing would be part of netperf's charter or not, but multithreading should be if at all possible.

right now I multithread netperf like so:

for ((i=1; i<17; i++)); do netperf -H 10.0.0.$i -t TCP_STREAM -C -c -P0 & done

however I don't get aggregate throughput unless I script up a bunch of awk/sed/bash addition magic.

Thoughts?
