Fun to see someone decide to just write a faster JSON parser because they believed it was possible. They mentioned last year that libjansson had some intermediate layer with Emacs, which led to too many memory allocations: https://lists.gnu.org/archive/html/emacs-devel/2024-03/msg00...
Thanks for linking to that thread. Was fun to peruse it reading the feedback and seeing how things went there. Huge kudos to Géza Herman for getting this in. Similar kudos to the the team on the review! Genuinely pleasant to read how that whole process went.
