I think smart contract execution is a good application of WebAssembly. It seems promising!

Thank you, that's a good summary of the article!
Even faster startup times can be achieved by so-called in-place interpreters that do not even translate the Wasm binary at all and instead directly execute it without adjustments. Obviously this is slower at execution compared to re-writing interpreters.
Examples for Wasm in-place interpreters are toywasm (https://github.com/yamt/toywasm) or WAMR's classic interpreter.

I am aware of Wizard and I think it is a pretty interesting Wasm runtime. It would be really cool if it was part of Wasmi's benchmark testsuite (https://github.com/wasmi-labs/wasmi-benchmarks). Contributions to add more Wasm runtimes and more test cases are very welcome.
The non-WASI test cases are only for testing translation performance, thus their imports are not necessary to be satisfied. This would have been the case if the benchmarks tested instantiation performance instead. Usually instantiation is pretty fast though for most Wasm runtimes compared to translation time.

FWIW there are a bunch of benchmarks we've put up here:
https://github.com/composablesys/wish-you-were-fast/tree/mas...
They run on nearly all engines.

There is also this (https://github.com/mbbill/Silverfir) and Wizard ().
I wrote a paper about Wizard's in-place interpreter and benchmarked lots of runtimes in (https://dl.acm.org/doi/abs/10.1145/3563311).
As there seem to be even more runtimes popping up (great job with wasmi, btw), it seems like a fun, maybe even full-time, job to keep up with them all.
