Topic: Slow Module Compilation

I'm using Module::from_binary and it seems that it is slow, or I'm doing something else that makes it slow. Any advice to speed it up or fix it?

The Module::from_binary API compiles the wasm module to native machine code, so if that's slow it's probably the compilation process that's slow. Would you be able to share the binary?

Glancing at the code there, looks like your WASM is a static module that doesn't change, so I'd recommend compiling the module once at program startup so that way each request doesn't have to recompile the wasm
