Asking for resources on networking code optimization

Hello !

Does anyone know good resources (books/parpers/posts/whatever) about optimizing networking code ?

In a project i'm currently working on, i'm specifically trying to optimize for low latency (not bandwidth) in the context of UDP packets exchanged over a WiFi network.

But i'm interested in any kind of resource on the broader topic as well. Searching the web gave many "vague" and non technical results...

Thanks !

Martin
