Red Hat Bugzilla – Bug 216311
emacs (including emacs -nw) VERY slow on startup
Last modified: 2007-11-30 17:11:49 EST
Description of problem: after new installation of FC6 emacs *with or without*
X starts up extremely slow. So slow that it is pretty much unusable.
This is new. I have been using Fedora since its first release and new had this
problem before. I really need emacs to work properly.
I found on the web to add
(modify-frame-parameters nil '((wait-for-wm . nil)))
to .emacs. This does not solve the problem
Version-Release number of selected component (if applicable): 21.4-17
How reproducible: always
Steps to Reproduce:
2. emacs filename
3. emacs -nw filename
Actual results: takes more than 30 seconds to start (in X mode and in no-X
Expected results: starts within ~1s
Additional info: this is new in FC6

Does emacs 22 have the same problem? You can get rpms from
me again. I thought the bug was fixed this week after an X (x-server, ..)
update that was released. However, it seems to be back. It worked for several
days. This is quite annoying. It comes and goes.
Ok, what I noticed is that the speed seems to be related to the WEP key enabled
wireless networking. Whenever I start emacs (X or no-X mode) with
wireless and WEP key enabled it's slow. On a nework w/o WEP key it's
fine. Is there anywhere a selinux or firewall switch/flag I need to
change for emacs?

Can you try reproducing your problem using
emacs -q --no-site-file
if that is also slow, can you also try emacs-22 which is available for FC-5 and
FC-6 at: http://people.redhat.com/coldwell/emacs/fedora/
You can try to identify where the slowdown is comming from by running strace...
This problem was fixed within the last two weeks or. One of the more recent
upgrades did fix the problem. Which one? I wish I new. This problem had been
bothering me for several months. Unfortunately, I have no idea how the problem
was fixed. Sorry.
Thanks for all the suggestions,
Had this problem with CD install of Fedora Core 6 with current updates.
