From: "Tomas Berggren" <Tomas.Berggren <at> configura.com> To: <emacs-pretest-bug <at> gnu.org> Subject: 23.1.91; mark text in c++ mode is painfully slow Date: Tue, 16 Feb 2010 16:48:37 +0100
[Message part 1 (text/plain, inline)]
I opened a file with about 3500 lines in c++ mode and started from the top marking the text with ctrl - space and then pressed arrow down or ctrl n to mark about 200 lines. The cursor pause after a few lines and hangs for some seconds with almost 100% cpu activity. This behavior did not appear in 20 and 22. I normally work in 23.1.1 but downloaded the latest beta to see if anything had been corrected. Not sure if this depends on the amount of code or if the support for Unicode made things slower, but since it worked fine on 22 something else might have changed. It might be by local setup as well. I hope this can be of any use, this is my first bug report after using emacs for 12 years!
