Feature-Request: use BufferManager and SocketAsyncEventArgsPool to optimize memory

[nguyentuan3691]

Hello

I used your project to create a socks5 server, it's a bit difficult to access your project structure but everything is fine. During long-term running on the server, I found that the project used a lot of ram and was not optimal. I think we should use BufferManager and SocketAsyncEventArgsPool to optimize memory usage.
