fwiw I live in [macOS emacs](https://emacsformacosx.com/) all day long for systems engineering (C/C++) and have 201 open buffers, an uptime of 57 days and ~540 MB memory usage.

I used to use that version of emacs, but performance issues on my Mac Studio made using it just untenable. I switched to Homebrew's "emacs-plus" which does not suffer, for whatever reason, the same performance issue. Based on TFA, I'm somewhat baffled as to why, but I can't argue with results.
I used that too, but have held back at 27.2 because all the following versions have been significantly slower.
It seems around that time they added some processing loop that really made things sluggish.

I also live in macOS Emacs built from source, currently running 31.0.50. Linux kernel dev over TRAMP w/ clangd language server, ~300 open buffers and <500MB memory.
