Project mention: Scaling to ~15K requests per second with Java – Part 1 | news.ycombinator.com | 2023-07-14

I remember a consulting gig where they were pushing 50k requests per second with PHP in a 2018 laptop by using this framework https://github.com/walkor/workerman
In a real application, with database connection pooling and auth sessions, it went down to 15k requests/s.
And that was PHP7. PHP8 introduced JIT so it's probably significantly faster these days and hopefully fully typed.
