If you need more info about that then someone will need to remind me what functions to use for measuring. Here's what I see: I put the cursor on, say, the first file or dir name in a large Dired buffer (1860 lines). I do `M-: (field-end nil)'. In Emacs 22, 23, and even 24.3, the result appears immediately - no perceptible delay. In recent Emacs 24 (e.g., this build), the result appears after several seconds - 3 to 4 sec. This is a really noticeable difference. It makes certain interactive interactions nearly unusable. Can something be done about this, or is it perhaps an inevitable consequence of some feature that has been added recently?
