To get quick profiles, that form of aggregate netperf is OK - just the one
iteration with background processes using a moderatly long run time. However,
for result reporting, it is best to (ab)use the confidence intervals
functionality to try to avoid skew errors.
Yes. My formal testing uses -i 50. I just wanted a quick testing. If I need
finer-tuning or investigation, I would turn on more options.
Netperf will silently clip that to 30 as that is all the built-in tables know.
Thanks again. I learned a lot.
Feel free to wander over to netperf-talk over at netperf.org if you want to talk
some more about the care and feeding of netperf.
happy benchmarking,
rick jones
