I have two C++ services that need ultra low-latency communication over the network. I’m considering using raw sockets with io_uring but also looking at possibilities of using various messaging queues like ZeroMQ, NanoMQ, and Aeron UDP etc.

My Questions:

1. How does the latency and performance of raw sockets with io_uring compare to ZeroMQ, NanoMQ, and Aeron UDP?
2. Is the added complexity of raw sockets with io_uring worth it compared to the simplicity of high-level libraries?
3. Can you provide sample code examples for implementing raw sockets with io_uring?

some code example so far i found is just this : https://unixism.net/loti/tutorial/webserver_liburing.html

but its http server and client, i probably dont need to have http as application protocol.

Any insights or benchmarks would be appreciated. Thanks!
