Performance dashboard is linked here https://ianm199.github.io/omnilua/performance.html.

In a mix of official and unofficial benchmarks wall clock performance is ~1.4x as fast as C Lua and the memory usage is ~1.7x.

So performance is worse to be clear but within range. There’s some performance improvements I haven’t gone for yet that would get it down to ~1.1 I think.

Heh I was going to queue up a skill that uses the CLI to make it easy to convert scripts to older or newer versions.

If you have any Lua use cases let me know I’m looking for more real world use use cases to justify the effort here.

Hmm I think in general I would not recommend doing this just because Lua does change pretty significant things from 5.1-5.5 so you could have some really hard to understand behavior if some portions are 5.1 vs 5.4 for example.

I think where it would be most helpful is converting a codebase and being able to easily run tests to ensure behavior is the same.

I created a github gist https://gist.github.com/ianm199/5ba0366376eca673142e1f0c79b4... that explains what is practical (I used AI for this to be clear feel free to skim).

Do you have a use case in mind? Would love to chat or take a look at an github issue if you create one.
