For me, it takes about 2 seconds on vanilla Emacs in an org-mode buffer, and a few minutes on my Emacs configuration (was almost instant before the offending commit). --=20 Sheng Yang(=E6=9D=A8=E5=9C=A3), PhD student Computer Science Department University of Maryland, College Park E-mail: styang@fastmail.com E-mail(old): yangsheng6810@gmail.com
