Subject: Re: Suggest use -e or --enhanced with iperf 2

Bob has put in a lot of work over the past few years on improving
iperf2's capabilities. The new bounceback tests and histograms are
great! I hope more folk here upgrade to the newer versions, and pour
through the man pages for the new options.

There is more to good networking than just throughput tests.
