aquatic VS libuv

How does Bitmagnet compare to Aquatic? https://github.com/greatest-ape/aquatic

I have a question on UnsafeCell usage that popped up while implementing io_uring support for aquatic_udp. I find the docs slightly confusing (in particular the part that I've marked in bold):

I've done a new round of benchmarking of open UDP BitTorrent tracker implementations. Results were great for aquatic_udp, achieving double the throughput of opentracker when running on 8 CPU cores:

If you run your tracker on Linux and an info hash whitelist approach would work for your use case, it might be worthwhile having a look at aquatic_ws [0]. It relies on tungstenite [1] for websockets and achieves around 20x the throughput of the reference implementation when running with four threads.

aquatic, a multithreaded BitTorrent tracker with world-leading performance

But aquatic_udp doesn't use glommio.. https://github.com/greatest-ape/aquatic/pull/29

aquatic is a Apache 2.0-licensed BitTorrent tracker written in Rust that I have developed over the last couple of years. It focuses on correctness, stability and high performance.

The udp request parsing code seems to have been copied from aquatic. Please note that the Apache 2.0 license requires attribution.

I wound up on a different team with pre-existing Python code so temporarily shelved my use of Go for a bit, and we used Sanic (an async Python framework built on top of the excellent uvloop & libuv that also powers Node.js) to build some APIs for live channel management & operations. We hand-wrote our OpenAPI and used it to generate documentation and a CLI, which was an improvement over what was there (or not) before. Other teams used the OpenAPI document to generate SDKs to interact with our service.

In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

Libuv, the C library that gives Node.js its asynchronous, non-blocking I/O capability is responsible for managing the thread pool. Node.js gives you the capability of using additional threads for computationally expensive and long-lasting operations to avoid blocking the event loop.

Node.js is written in C, C++, and JavaScript. The core components of Node.js - the V8 engine and the libuv library - are written in C++ and C, respectively, since these languages provide low-level access to system resources, making them well-suited for building high-performance and efficient applications. JavaScript is mainly used to write the application logic.

Notably upgrades to libuv 1.45 which has io_uring support. Faster file system access! Awhh yeah, it's on.

Remarkable what a mild & unintrusive PR adding io_uring was. https://github.com/libuv/libuv/pull/3952

Well, the single-threaded nature ultimately leads to its biggest downfall. Node.js utilizes a synchronous event loop engineered using Libuv that takes in code from the call stack and executes it.
