Subject: bug#2056: 23.0.60; Enabling flyspell degrades performance
Date: Mon, 11 May 2009 21:41:51 -0500 [thread overview]
Message-ID: <0941AF04-D179-4244-A5D1-8488E4B13D7B@me.com> (raw)
Confirming that this behavior is still present using:
GNU Emacs 23.0.93.1 (i386-apple-darwin9.6.2, NS apple-
appkit-949.43) of 2009-05-11
I have the following in my .emacs:
(load "/Users/marcschwartz/Downloads/Emacs/flyspell/flyspell")
(autoload 'flyspell-mode "flyspell" "On-the-fly spelling checker." t)
(add-hook 'tex-mode-hook 'flyspell-mode)
(add-hook 'text-mode-hook 'flyspell-mode)
This is on a fully updated unibody MacBook Pro with OSX 10.5.6.
If I comment all of the above lines, the performance of emacs is fast
when editing and scrolling through a large file. If I leave the lines
as is, or comment the last three lines and manually enable flyspell
mode after emacs has started up, all scrolling and general cursor
motion slows down to a crawl.
I disabled the toolbar, as per comments in various posts, but that has
no effect on emacs performance. This seems to be solely related to the
use of flyspell mode.
I should also note that this same performance hit occurs with the
Aquamacs devel branch built from their git repo, which is based upon
emacs 23. The current release Aquamacs 1.7, which is based upon emacs
22, does not exhibit this behavior.
