Subject: A significant slowdown calling font-lock-fontify-buffer from a hook
Date: Tue, 16 Jul 2013 02:12:40 +0200 [thread overview]
Message-ID: <CAAeL0SSqSShXtsnqfkiF3H9n+OxYwuJ4yi6ci=wwfdnb8JpqcQ@mail.gmail.com> (raw)
I discovered this because I call colum-marker-1 (from
colum-marker-mode, http://www.emacswiki.org/emacs/column-marker.el) in
the prog-mode-hook, but the issue is with font-lock-fontify-buffer.
emacs -Q --eval "(add-hook 'prog-mode-hook
#'font-lock-fontify-buffer)" src/xdisp.c -f kill-emacs
On Emacs 24.3, -O0 -g3 --enable-checking: about 2 seconds.
On trunk, -O2 -g3 --enable-checking: ~ 33 seconds, x16 slowdown.
Any idea what could be causing this?
