There is generally a substantial pause when I delete words however (kill-word or backward-kill-word). Actually, kill-ring-save (M-w) also exhibits horrible performance, so it appears not to be a strictly display-related problem. Does copying text to the kill-ring involve a lot of X clipboard activity? Should it matter, I'm running on a Mac, BTW, using Apple's XQuartz 2.1.6 (xorg-server 1.4.2-apple33).
