I run a Rust webserver on a literal Pi3 in my basement and I think I managed to bench it up >1000 rps for standard loads. And that includes a bunch of tanvity querying as well.

I suspect I could do 3000+ rps with some tuning and a more modern CPU or hetzner VPS, but there's some fun cachet from running on an old Pi while there's still headroom.
