  I had been regularly tracking the performance of org-mode for big files, e.g. 
a 18 Mb one with 380k lines (created only to test this).

  1. With last month's org-mode in emacs 24 I needed more than 5 minutes to 
open it, and then moving around the file was too slow to be comfortable (local 
editing was however acceptable).
  2. With the current one, it's only 10 seconds loading time, local editing is 
still fast, and jumping around sections takes at most 2 seconds per move.
  So this change has made me stop worrying about files growing too fast, at 
least for many years. Thanks!
