In my app, I use WsWebSocketContainer to create websocket client.
As the number of sessions increases, memory usage also increased. So "OOM Killed" occured frequently.
I know that It is a normal situation in thread-per-connection model which is current applied.
Current model have advantage that It is very intuitive and sometimes it behaves like kind of rate limiter.
But I think that threads for R/W may not working busy in some case.
Also platform thread will be created twice of session count and it allocate a lot of default stack memory.
furthermore context switching cost expensive too when using platform thread.
So I think that instead of create two platform thread per session, using virtual thread will be helpful in some cases.
Since I may not understand overall about websocket codes and architecture, I just create draft pull request.
Adding choice to use virtual threads would be helpful for optimizing memory usage.
