So there's an easy workaround but it wasn't easy to find. From casual profiling, the issue seems to be the thousands of `put-text-property' calls in `insert-directory'. Steps to reproduce: wget http://www.emacswiki.org/cgi-bin/wiki/dired+.el/download/dired+.el [add directory containing dired+.el to load-path] emacs -q (require 'dired+) (setq font-lock-support-mode nil) (dired "/usr/bin") Thanks for the report. I'll look into this. BTW, dired+ is not part of standard Emacs, so this is the wrong place to post bugs about it. Please post dired+ bugs here: http://www.emacswiki.org/cgi-bin/wiki/DiredPlus, or email me directly. Thanks.
