pepyakin opened PR #1965 from ser-host-func-opt to main:

We, in paritytech, had to momentarily fork wasmtime due to lack of support of sharing Modules between threads. Now, with the recent changes landed it is possible for us to return to the upstream!

One of the changes we had in our fork is similar to the presented here. Namely, we noticed a performance increase for our workloads if we avoid allocations for a common case if the number of arguments doesn't exceed some threshold.

In our fork it wasn't using smallvec, but I don't think it's worth the hassle avoiding it since smallvec is already used by cranelift.
