Great analysis on all the runtimes.

I love all the improvements that Wasmi has been doing lately. Being so close to the super-optimal interpreter Stitch (a new interpreter similar to Wasm3, but made in Rust) is quite impressive.

As a side note, I wish most of the runtimes in Rust stopped adopting the "linker" paradigm for imports, as is a completely unnecessary abstraction when setting up imports is a close-to-zero cost

Thank you! :)

when using lazy-unchecked translation with relatively small programs, setting up the Linker sometimes can take up the majority of the overall execution with ~50 host functions (which is a common average number). We are talking about microseconds, but microseconds come to play an importance at these scales. This is why for Wasmi we implemented the LinkerBuilder for a 120x speed-up. :)

I see [1], thanks for sharing. I'll need to dig a bit deeper in your implementation!
