One guess: this file has one line of text which is spelled WITHOUT linebreaks at a length of 405000 characters!

So obviously the problem is rooted in this fact. Maybe syntax highlight is slow on such long lines, or something else. Yet I’ve noticed this a long time ago – EmEditor is slowed down on this very occasions (if the text lines would have a reasonable length then Search & Replace would take a few milliseconds to finish)
