  • BTW, I liked the idea on emacs-devel about PGO/FDO experiments. And, with a short PGO Emacs session and compiling Emacs with that profile, I see almost all the responsiveness issues disappear. What is left are slow indent-region and slow file opening, which seem unrelated to UI responsiveness.

    Are there automated UI test runners? Just a matter of recording macros, or even writing out elisp, I guess. Having targeted tests and using them for PGO/FDO to do Emacs releases seems useful.



  • My ₹1. It may depend on what you plan to write in it (for fun). The BEAM sounds great for long-running processes, but not as much for point tools; Erlang and co supposedly run slower than Python, which isn’t fast either.

    My other ₹ ;-) if you stick to the BEAM: OCaml sort of runs on it, as there is the Caramel project to replicate it (https://caramel.run/). One of the Erlang creators also ported Prolog to the BEAM (erlog), as well as Lua (erlua) and Lisp (LFE). Elixir is probably great, as it is inspired by Ruby (I found Ruby very pleasant, other languages have so much semantic noise).

    Freebie! The BEAM inspired an inspirational design for parallel programming, the Pony language. I am somewhat sad development slowed down, it is a Rust killer.









  • What hardware/VM and OS are you running on? What kind of development do you do in Emacs?

    And, are you normalizing having to read the docs to have, for example, indent-region not be too slow?

    I agree native-comp shouldn’t be necessary, since Emacs wasn’t this slow until maybe Emacs 25 and they keep improving the Elisp interpreter. And we probably can’t expect the speed from before the CPU vulnerability mitigations and from running on hardware from any software running in VMs nowadays.

    What I see is much worse than that.
