Large buffers are fine - long lines are not.

If you don't have long lines but you are experiencing slowdowns on large buffers, your mode is doing something. As an example, large XML files bring my Emacs to a crawl, but if I switch to a text mode it's fine.

For long lines, I believe the latest Emacs has a fix: https://www.reddit.com/r/emacs/comments/ccoksw/solong_mitiga...
