Version: desconocido (using 4.2.1 (KDE 4.2.1), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.27-11-generic I use the message list view "Current activity, mail thread mode". My personal folder (a local folder where I store POP mails) contains more than 10000 messages and more or less 5000 threads. Each time I click into this folder Kmail takes long time by doing "Groupping XXXX mail threads of 5000". Is it required to do this process each time? couldn't it use a cache? Note that I'm using Kmail 1.11.1 which includes he new message list view.
Yes, grouping seems to be a little slow indeed. Threading is OK. As a workaround, you can choose a different aggregation which doesn't use grouping, like "Standard Mailing List".
Thanks, it is a good workaround unitl groupping is improved. BTW, I didn't see the category "new message list" when reporting the bug (via "Report bug" entry in "Help" menu of Kmail.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
