I was just told that I should state here that I am the author of the article, please ask me anything. :)

For startup performance Wasmi and Wasm3 are both the fastest engines according to the benchmarks. For execution performance you are right that generally JIT engines are expected to be faster than interpreter based Wasm engines.

Also, as stated in the article, on Apple silicon Wasmi currently performs kinda poorly but this will be improved in the future. On AMD server chips Wasmi is the fastest Wasm interpreter.

I see that this sentence was a bit vague. What was meant that Wasmi as a Rust library mirrors the Wasmtime API that can be found here: https://docs.rs/wasmtime/21.0.1/wasmtime/

But yes, Wasmi also supports WASI preview1 and can execute Wasm applications that have been compiled in compliance to WASI preview1.

yep, the title somehow got cut at the end :S
