Version: 1.9.1 (using KDE 3.5.2, compiled sources) Compiler: gcc version 3.4.4 [FreeBSD] 20050518 OS: FreeBSD (i386) release 6.1-PRERELEASE Simply shift-deleting a message from my mailbox (4000+ messages) takes noticably long time, during which the kmail process can be observed with top to take over 40% of the CPU. This is when the messages are listed in thread-branches. I guess, the whole mailbox is rescanned to rebuild the branches, but 4000 messages is not that many. Even if they are all rescanned, it should still be instantanious on a Pentium-4 running @2GHz. Perhaps, some linear scanning needs to be replaced with in-memory hashtables somewhere? :-)
This is related to bug 87857. Let's see if there is any improvement after that patch is (if done so) merged.
As the mentioned other problem has been fixed a long time ago, and we're already at KDE 4.3.1, can you still see this problem ?
Hello! Sorry to be the bearer of bad news, but this version of Kmail has been unmaintained for many years so I am closing this bug. Please try using the latest version of Kmail to see if your issue persists. If it does, please submit a new bug in "kmail2". Thank you!
