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).
