It's possible to determine good values automatically: Measure your typing speed.

You can do it in the background with:

and periodically update the latency parameters to be just over your natural typing speed.

I just chose to use an editor whose very architecture doesn't require nonsense like this so the editor doesn't freeze on me.

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... )
