Open a latex file for which "M-x occur Ret the Ret" gives about 3000 hits. If the source buffer is fontified, it takes about 2 seconds until the occur-buffer pops up, a time that is about 7 times longer than starting the Emacs app! On the other hand, without fontification of the source buffer, the occur buffer pops up almost immediately. Setting the user option "occur-mode-hook" to nil has no effect on this difference.

I tried this in a tex file with about 2700 "the" matches, and it took
about half a second whether font-lock-mode was on or not (I assume
that's what you mean by "without fontification").
So I'm unable to reproduce this problem. Are you still seeing this in
newer versions of Emacs? If so, do you have a test file that
demonstrates this problem (starting from "emacs -Q")?

More information was requested, but none was received, so I'm closing
this bug report. If this is still an issue, please respond to the
debbugs address and we'll reopen the report.
