@songjiayang I would really love to see this implemented!

Have you done any research in how to handle UDP messages in high performance scenarios? It seems like this could be highly variable.

If you are copying across threads but only having one user that could take up a lot of extra CPU vs cases where it does make sense. If you are interested would love to work on this together. I am going to start using pion/turn in a high usage production environment at work and really want to see if I can beat other TURN servers performance wise.

thanks!

I have done a benchmark test, but not too much improvement 😄 .

This should be resolved by the example of a multi-threaded server which has been merged in #295
