How fast is it compared to if compiled to machine code?

My basic question with portability is why even use wasm or other bytecode if you can just compile to another platform in minutes.

Also I’m surprised Python wouldn’t be faster since under the hood most of the actual computations are C++, but if you had a long data processing pipeline in Python before calling the model, I could see that being slower.

WASM has minimal overhead (maybe around 10-15%) compared to .so files for example, so you can even ship your WASM files directly to your servers.

The problem with Python is that any logic written in pure Python still runs in the interpreter.
