Description

I know benchmarks can be highly dependent on a number of variables, but I also recall seeing stats for how many connections ws could sustain (e.g., wsbench results), would it be possible to have these metrics available?

The answer is to run your own benchmarks. As a rule of thumb, the overhead over a plain net.Socket in terms of performance is around 10%. I'm not sure about memory usage, I have not run a benchmark for this in a long time.
