C# Networking Deep Dive with io_uring part 5 - Threadpool Rant
The article discusses the author's experiences and opinions on using io_uring for networking in C#. While io_uring excels in micro benchmarks, the author argues that it may not be the best fit for typical backend applications due to its reliance on single-threaded execution. The piece highlights potential deadlock issues that arise when integrating io_uring with the .NET thread pool and async/await patterns.
- ▪The author has been researching io_uring for seven months to evaluate its effectiveness compared to epoll for networking.
- ▪While io_uring is fast in micro benchmarks, it can lead to deadlocks in typical backend scenarios when used with the .NET thread pool.
- ▪The article emphasizes that the performance of io_uring is conditional on the reactor being the sole submitter of the ring.
