Re: [Bloat] Netperf re-licensed as MIT

[Dave Taht <dave.taht@gmail.com>]

so glad to hear the license has been fixed.

carl, iperf is only used in a few of flent's tests. We trusted netperf
- as did the linux kernel developers - a lot further than all the
iperf variants combined - at the time we started work on flent.

I would not mind us somehow developing a drop in replacement for
netperf, perhaps leveraging the irtt codebase, as I have a long
standing desire to be able to reliably measure latencies and the
output of TCP_INFO in "some" tool below 250us.

iperf has come a long way, but getting to where I could trust the
largely "academic" codebase it was would take a ton of benchmarking.
