There’s now an interpreter in wasmtime called Pulley. It’s an optimizing interpreter based on Cranelift, which generates interpreter opcodes which are more efficient to traverse than directly interpreting the Wasm binary.

I have run wasmtime on the esp32 microcontrollers with plenty of ram to spare, but I don’t have a measurement handy.

That is amazing news! Thank you.
