This article implements a queuing system that achieves higher concurrency performance by swapping buffers. In certain production-consumer scenarios, it can replace Go's built-in channel to achieve better performance. The code is simple and easy to understand, with only around 200 lines. The inspiration for this project comes from an article titled 'How to Avoid Overreliance on mpsc' at https://blog.digital-horror.com/blog/how-to-avoid-over-reliance-on-mpsc/. You can find the repository at https://github.com/doraemonkeys/fast-mpmc. This solution can significantly improve the performance of your application by reducing the overhead of Go's built-in channel. It's highly recommended for developers who want to optimize their concurrent systems.
