Well, in my real-life case it is a little complicated. I often editing
files other than English, besides that, I use Emacs doing a lot of
things, such as Gnus to read news and Twitter-mode to read tweets.
Please assume all these jobs involve multiple languages. So if one
content makes Emacs slow down, then it seriously affects my daily
Emacs usage.
