script-bench-rs

khvzak has compiled some benchmarks. mlua and roto are some of the fastest: https://github.com/khvzak/script-bench-rs

Thanks! > When you made Roto what kind of workloads were you optimizing for? We're building a BGP collector with custom filters written in Roto. Imagine a database that constantly receives updates and we want to filter (or transform) those messages based on a script. > How are you guys benchmarking performance? Actually, we haven't done that much as feature work has been more important than optimization. There's a lot of opportunities for optimization left on the table. There are a few benchmarks that we have done: - A very naive fibonacci computation, where we were faster than Lua, - There's this benchmark with a lot of string manipulation made by somebody else where we roughly match Lua: https://github.com/khvzak/script-bench-rs - There's the testing done with Iocaine, where Roto is apparently much faster than Lua. The scripts there do

Hi, I'm another one of the maintainers on the project. In general, we are shifting more to performance now than conformance. We currently sit at around 94% conformance, so there's not really that much more to go conformance-wise. The remaining conformance gains are a couple of the newer specification features and Intl related features. Our current conformance can be found at https://boajs.dev/conformance. Regarding performance, we are already making some gains, with hopefully more to come. The best example of this was probably the updates to script-bench-rs with our most recent release (which can be found at this commit https://github.com/khvzak/script-bench-rs/commit/d9635de77d2...). We still obviously have more to improve on, but we have already made some pretty steady progress from where we were. EDIT: I forgot to answer your question

But if this benchmark is right, then wasmtime is 5x faster than wasmi for it: https://github.com/khvzak/script-bench-rs

I started on a Rust app that uses SDL3 and lets you script it via embedded V8[1]. But I'm very seriously tempted to fork it and embed wasmtime or wasmi and let you script it in anything, and include a few wasm compilers into the app for convenience so you just give it a file and it does the rest. Mainly because of the speed of wasmtime and wasmi compared to alternatives[2]. But my biggest concern is that this isn't adding any real convenience. You still have to set up whole code environments, which defeats the purpose of scripting it. Still, it's such a neat idea that I don't want to not do it, and I just might.
