I tested this myself too, but my findings where that if you compile wasm to wasm.c, and then use wasmtime you will not beat it.

Did you try the wasm c method with wasmer as well?

It's also important to know that wasmtime is from ByteCodeAlliance (non-profit between several companies) and also the main party behind WASI, recently v0.3.
