@nprofile…sju6 @nprofile…6kk0 You might be pleased to hear that work on a new code generator has continued! @nprofile…xsrr is driving the development: https://github.com/leanprover/lean4/pulls?q=is%3Apr+author%3Azwarich. I'm sure he would be interested in performance experiments once it's ready. The current codegen is best thought of as "just what we needed to bootstrap Lean in the first place".
