I (used to) use it almost exclusively with eglot lsp to python language server (Jedi I think). I run emacsfoacosx 29.2 and now .3. And I’ve used it since 1996 on emacs 18 on a b/w sun workstation.

But most recently on the last 2020 intel MacBook Pro.

The cursor moving speed through a source file is atrocious. Maybe 3 - 4 lines per second vertical and similarly horizontal.

The shell just freezes on long lines and forget about font lock for multi MB json.

All of these tasks would be hard a decade ago but now aren’t even table stakes.

It just /feels/ sluggish.

I reluctantly just gave up. It was fast way back then but I think workloads have changed. I tried zed for a bit but have now reluctantly gone to pycharm CE. If you accept the different windowing metaphor and add bindings for C-a and C-e and friends (some are standard) it’s not bad. And never sluggish (same hardware).

I love emacs but for my outlandish workload of python programming and wrangling multi MB text output it just doesn’t perform.

I speculate it isn’t straight line speed but threading that is hurting perceived latency.
