Any colyseus benchmarks? - web framework currently used?

[onelsonic]

Hi everyone.
Colyseus looks pretty neat.

Can anyone confirm, @endel maybe? what is the current web framework used by colyseus?
Is it express :
https://github.com/expressjs/express
or uWebSockets :
https://github.com/uNetworking/uWebSockets
or something else?

And are there any benchmarks available for colyseus using wrk ?
https://github.com/wg/wrk

This is to evaluate the performances of colyseus.

Here is a list of tested web framework :

Thank you
and have a nice day
