auto-complete is really fast in emacs-lisp buffers but slow in text-mode buffers

[Eric S Fraga]

Hello,

I have been using auto-complete 0.2.0 and it works very well generally
but for some reason did not work in org-mode buffers.  I decided to
upgrade to the latest stable version of auto-complete, version 1.3.1.
This new version works in org-mode buffers so I'm happy in this regard.
However, it is very very slow in org-mode and text-mode buffers yet fast
in emacs-lisp buffers.

Does anybody know what could be the cause of the difference in speed?
The settings, as far as I can tell, are global so they should apply to
all buffers equally?

My actual relevant settings are:

--8<---------------cut here---------------start------------->8---
(require 'auto-complete)
(require 'auto-complete-config)
(ac-config-default)
(setq-default
 ac-sources '(
	      ac-source-abbrev
	      ;;ac-source-dictionary
	      ;;ac-source-symbols
	      ac-source-words-in-all-buffer
	      ac-source-words-in-buffer
	      )
 )
(setq
 ac-auto-show-menu 0.1
 ;; ac-auto-start 3
 ac-menu-height 20
 ac-modes (append ac-modes '(org-mode jde-mode latex-mode ledger-mode mail-mode message-mode text-mode))
 )
(global-auto-complete-mode t)
--8<---------------cut here---------------end--------------->8---

Thanks,
eric

Apologies; I should have added that I am using emacs version 24.0.50.1
(Debian emacs-snapshot from a couple of weeks ago).  This may or may not
be relevant, of course...

Thanks,
eric

and further apologies: problem sorted!  The problem is caused by
flyspell-mode.  There is a workaround, imaginatively named
ac-flyspell-workaround!  Invoking this command solves the problem and
auto-complete works like a charm now!

Sorry for the noise but maybe this will help others in the long term.

Thanks for listening,
eric

Maybe you could ask the auto-complete guys to M-x report-emacs-bug about
the flyspell.el problem so that the workaround can be dropped in some
future version?
