One thing I'm wondering about: what's the call overhead of wazero? Especially for function calls (rather than as a `system()` alternative)?

I understand that cgo has significant per-call overhead, aside from all the other curses it implies, does wasm/wazero have the same issue or not?

With the version of wazero I'm using right now, it's about 0.3 milliseconds to do a single call from Go to Rust and back in the best case on my hardware. I am told that a recent patch to wazero will increase this by a lot, so I'm going to try upgrading to that patch and see what differences it makes. I still think that it will be a bit slower than cgo, BUT the platform-independence and strict sandboxing makes up for it in my book.
