Hi.
I have a shell script which exports my agenda to a file. It's pretty
slow: about 90 seconds. There are many files (200 .org files, 76k
lines, 3'6 Mb, 1600 open tasks) but the performance should be better.
I found a way to bring it down to 11 seconds: temporarily disable
the version control tools I'm using (bazaar, git). To test, just
change their names so that Emacs can't run them.
Since this slowness is caused by vc-mode, I wonder if it's possible
for Org to open the agenda files without enabling vc-mode, for vc-mode
is not necessary for org-mode.
I fear not, because org-agenda-get-day-entries uses
org-get-agenda-file-buffer to open a buffer normally, and this buffer
should be fully functional for later usage.
As a hack, I used (defun vc-find-file-hook () nil) in my script;
this does the trick.
Greetings,
Daniel

That's indeed the problem: Its hard to figure a default options for
such functionality.

Instead of overloading `vc-find-file-hook' you could use something
like this:
(defun dmj/disable-vc-for-agenda-files-hook ()
"Disable vc-mode for Org agenda files."
(if (and (fboundp 'org-agenda-file-p)
(org-agenda-file-p (buffer-file-name)))
(remove-hook 'find-file-hook 'vc-find-file-hook)
(add-hook 'find-file-hook 'vc-find-file-hook)))
(add-hook 'find-file-hook 'dmj/disable-vc-for-agenda-files-hook)
It removes vc-find-file-hook from the list of find-file-hooks when the
file is question is an agenda file.

I suspect part of the problem is that vc-mode is slower than it should
be. Probably almost all of this time is 'git status foo.org' to find
out if the buffer gets a * or not. Perhaps a variable to vc-mode to
omit that part would help, but I don't really know.
