Subject: CC Mode 5.28 (C++); Huge Performance Problem
Date: Wed, 08 Oct 2003 14:39:50 -0400 [thread overview]
Message-ID: <76u16jlgjt.fsf@newjersey.ppllc.com> (raw)
Upgrading from this version of cc-mode (5.28) as delivered in the XEmacs
Package v1.33 my performance is fine. Upgrading to the latest cc-mode
version as deliverd in XEmacs Package v1.40 ( cc-mode 5.30) causes a huuuge
decrease in scrolling performance. XEmacs becomes remarkably unresponsive.
Simply doing PgUp or PdDn has appx a 1.5 to 2 second delay. All other
packages, including font-lock (in case that is relevant) are at the latest
revisions. Only cc-mode displays this problem and only in releases greater
than 5.28.
I don't monitor the bug-reporting mailing lists so I would appreciate a reply
back to my email address. Thanks!
