Real-world benchmarks

[uazu]

It would be good to do some real-world benchmarks to demonstrate Stakker's single-threaded approach versus other solutions, to show pros and cons.

Really any kind of real-world load would be good for a benchmark, but a suggestion from @d4h0 was a Websocket client or server:

• It appears that tungstenite crate should work on top of Stakker
• Probably the test can be load-balanced externally across several Stakker threads
• More ideas on this discussion
