Looking for help deciding which library to use for networking
message-io: a networking library meant to be very simple, built on mio.

Crate to build network packets over UDP
Another one I know about, but have not looked into yet, is message-io.
- Is there a proper websockets server framework in Rust?

Netty-rs - small rust library to easily write server/client networking protocols at application level
I'm working in a transport network library that possible fits as a building block for yours and solves the problem of using different underlying transports: message-io

Announcing message-io 0.12 - an event-driven message library to build network applications easy and fast. Now with zero-copy write/read messages. Performance close to using native OS socket with all the facilities the library offers.
Here is benchmarks

Someone built a chat backend with Rust for a production website?
I think https://github.com/lemunozm/message-io can be a good candidate.

message-io: an event-driven message library to build network applications easy and fast. Now with WebSocket support
The idea behind message-io is not to populate a current transport with a lot of options/profiles/modifications... this obfuscates the default way of working with it. Instead, if you want to build some behaviour on top of it, it is as easy as making an adapter! Following this pattern, you can split the way of using the library from the behaviour of the transport, keeping the things simple.

termchat: Terminal chat application on LAN with file transfer and ASCII webcam video streaming support. Built on top of tui-rs and message-io crates
The initial purpose was to show the capabilities of https://github.com/lemunozm/message-io Nevertheless, Termchat is growing and needs to polish some of its features. At this point it is not for real-world use but I hope to reach this target.

New scalable, fault-tolerant, and efficient open-source MQTT broker
We use Netty (https://netty.io/) as the source of the MQTT communication, and we build the MQTT features the MQTT broker should support ourselves on top of that.

Modern Async Primitives on iOS, Android, and the Web
In this space, we also have the somewhat related term blocking. Java's NIO library is one well-known non-blocking tool used for managing multiple tasks on a single Java thread. When listening to sockets, most of the time a thread is just blocked, doing nothing until it receives some data. So, it's efficient to use a single thread for monitoring many sockets, to increase the likelihood of the thread having some actual work to do. The Selector API does this but is notoriously challenging to program well. Instead, developers use frameworks like Netty which abstract some of NIO's complexity and layer on some best practices.

An investigative journey through concurrent data structures
DirectByteBuffer exhibits an intriguing behavior: it deallocates its backing memory during the finalization process, which occurs after garbage collection (GC) cycles. This poses an issue if your system is conservative with on-heap allocations, leading to infrequent GC cycles. In such cases, there could be a significant delay between the time the memory becomes unreferenced and when it is actually deallocated. This behavior could, in some respects, mimic a memory leak.
This is why some libraries hacks into DirectByteBuffer to deallocate memory explicitly, bypassing the finalizer altogether. For instance, the Netty library has implemented such a workaround, see Netty as an [example](https://github.com/netty/netty/blob/795db4a866401aa172757b95...).

Scaling to ~15K requests per second with Java – Part 1
Apologies replying to myself, but Netty, which underpins many of the popular Java backend frameworks, see backward compatibility as more important than supporting green threads.
https://github.com/netty/netty/issues/12816
It'll be interesting to see who (if anyone) picks up Netty's mantle in the Project Loom world.

Lessons learned from picking a Java driver for Amazon ElastiCache for Redis - Part 2
Given the fact that Lettuce is built with Netty, we also immediately noticed quite an impact on the initialization time (cold start) of our lambda function. Netty is really fast while executing, but takes a bit of time to initialize. The new Lambda Snapstart functionality might help with that.
