Hello.

I saw on many posts and implementations for TCP connection management managed using GenServer or GenStatem, which is great with all the message passing, reactive, etc…
However, it can have strong risk of bottlenecks and overloading of the mailbox;

I ran some benchmarks, and tested an implementation of a TCP client using ETS to manage the socket.
Even if it’s not use message passing and synchronous reading of the socket, it still way faster, and even more when we add load or parallelization. So I don’t get timeouts easily.
It seems also a win/win as there is no need or less for process pooling, which tends to reduce the overhead.

What do you think about managing TCP connection by ETS ?

Thanks
