Ho Bob,

+1 for renaming; the iperf2 iperf3 things is really confusing for mere end users.

However "next generation/NG" is a relative moniker, in a few years NG is going to be the new normal and hence the name misleading again.

While somewhat lame, maybe "iperformance" might be better in side stepping the-bigger-is-better issue when including numbers in the name, or obviously the correct answer go directly to iperf42 ;)
