You know what makes Emacs feel slow?
Corporate EDR BS.
I thought Emacs was terrible to use until I realized it was extremely fast on my home computer. All the pauses that EDR does combined with Emacs mostly single threadedness is a bummer. I still daily drive it now for my IDE at work because it's workflows work better for me than others, but it is such a bummer.
Do you notice this on macOS or Linux?
I definitely notice an EDR tax on macOS generally, but I haven't noticed Emacs having issues specifically. It's usually certain I/O operations like Git or tarball extraction that become slow.
(I think EDR here means https://en.wikipedia.org/wiki/Endpoint_detection_and_respons... )
