You're welcome! Oh, I forgot my most recent tool:

https://github.com/johalun/pperf

It's similar to iperf and useful for simulating many clients making 
short connections to ranges of IP addresses. The source code is 
ridiculously short and simple, showing how powerful Rust is when writing 
(safe and bug free) multi-threaded programs (of course with the use of 
some 3rd party crates).
