Pushing a naive C++ web server implementation to 9k req/SEC

Hacker News

Hey HN, I've spent the last few years doing web/desktop/IoT dev and I'm currently pivoting to low-latency/Quant. I built this as an exercise to see how far I could push a standard blocking C++23 socket architecture before the OS became the bottleneck. I covered zero-copy parsing, struct alignment, and Gather I/O. I'm currently working on tearing this down for an io_uring/kqueue rewrite for Part 2. All of the code can be found at GitHub ( https://github.com/TDiblik/cpp-web-server ) where I have a README documenting the process of optimizations and where I'll implement the mentioned enhancements in the future. Would love any feedback from here and/or people in the industry!
