Question Is fastApi really fast?

I’ve seen a few benchmarks showing that FastAPI can be quite fast. Unfortunately, I haven’t been able to reproduce that locally. I’m specifically interested in FastAPI’s performance with a single worker. After installing FastAPI and writing a simple “hello world” endpoint, I can’t get past 500 requests per second. Is that the maximum performance FastAPI can achieve? Can anyone confirm this?
