Since CVS 2009-01-30, Emacs.app here becomes very slow, and CPU consuming,
especially for w3m (often freezes more than 30seconds with 100% CPU)
I try to trace what the issue is. And find that it only relates to the Emacs excutable:
"/Applications/Emacs.app/Contents/MacOS/Emacs"
If I replace it with the excutable of 2009-01-29, everything backs to normal.
(which means that lisp/site-lisp parts are no problem)
I notice that there are some changes in CVS/emacs/src 3 to 4 days ago,
but I am unable to trace/debug it further. Can you look at the changes to
see what might cause the issue? (or any advice for me to further debug it)
Cheers,
poppyer

I have not noticed performance problems here but there have been
significant changes from 01/28 through today 02/04 and it is possible
there are problems under some usage conditions. First, could you
test again using current CVS (including 02/04 changes)? Also, is
there an easy way to obtain the 100% CPU usage cases in a mode that
comes with emacs? What OS X version are you on?
thanks.

Yes, today 02-04 is the same, and I am using OSX 10.5.6.
I am sorry but I am unable to reproduce it in other simple setup.
However, we seem to trace down that the issue is about regular
expression matching, as also mention in:
http://lists.gnu.org/archive/html/emacs-devel/2009-02/msg00012.html,
there are some clue about function "re-search-forward"
I profile in my w3m case, with exactly the same procedure here comes:

Is there any specific changes in regular expression part in 2009-01-30
(not about lisp but the Emacs executable)?

This was a problem on all platforms and I believe it has now been
fixed by a check-in 2009-02-07. Please let me know, thanks!

OK, thanks. There were no OS X-specific changes in the RE area, and
it sounds like other platforms are experiencing similar issues.
