I've made some quick benchmarks with eigenmath on my workstation (I couldn't be bothered to make sense of giac's build system to spit out a wasi-compliant wasm build). For reference, wasmtime is an Apache 2.0-licensed JIT runtime and wasm3 is a MIT-licensed pure interpreter. Both could be embedded in the HP Prime calculator, although wasmtime might not be available for the HP Prime G1 CPU and also for platforms that forbid JIT compilation, like Apple's iOS.

What do you think of these performance numbers?
