I guess you are referring to wizer [1]? (it's the closest to snapshot restore in the WebAssembly world). In case you are referring to that, the wizer strategy is valid for any Wasm runtime (and it will be fast once the Wasm module is snapshotted by wizer).

If you refer towards Wasm module loading times (once a module is already been precompiled), Wasmer is already one of the fastest ones.
