- acqq 3y ago"Only 35% slower overall than LuaJIT" as per video from a month ago. No idea which kind of tests are these "overall" though. https://www.youtube.com/watch?v=HxSHIpEQRjs https://www.youtube.com/watch?v=HxSHIpEQRjs Slides (pg. 31 performance): https://github.com/brandtbucher/brandtbucher/blob/master/2023/10/10/a_jit_compiler_for_cpython.pdf https://github.com/brandtbucher/brandtbucher/blob/master/202...
- dralley 3y agoI think that was a from an application of the technique to Lua from the original research paper.
- dataking 3y agoThe paper on copy-and-patch compilation [0] may give you a general idea although they didn't apply their technique to CPython. [0] https://fredrikbk.com/publications/copy-and-patch.pdf https://fredrikbk.com/publications/copy-and-patch.pdf
- dist-epoch 3y agoFrom the youtube talk it will be a small improvement (5-10%). It's more of a proof of concept for future things.
