That's my experience as well. Recently I rewrote a Golang-based QUIC server in Rust and I had a hard time getting it to perform equally well. Certainly possible but requires a lot of hand-tuning and knowing exactly what you do. In Golang you just spawn a Go routine for each request and avoid lock-based shared state as much as possible and you're mostly good, the runtime will manage all aspects like number of threads, allocations etc. for you.

One area where Rust is still better are memory-constrained environments e.g. on mobile and on microcontroller, though there's tinygo and the Go runtime gets slimmer as well, so now you can have binaries and memory footprints smaller than 5 MB on most mobile platforms, which is absolutely acceptable even for budget phones. I think Tailscale e.g. runs their modified version of wireguard-go on all mobile clients without issues.
