Bug ID: 333855 Summary: Kmail gets extremely slow having ~20k mails in a folder Classification: Unclassified Product: kmail2 Version: 4.11.5 Platform: openSUSE RPMs OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: message list Assignee: kdepim-bugs@kde.org Reporter: k...@teledigit.eu I have detailed folder tree (~40 folders) some of them having ~20k mails (~100k mails sum). Selecting a new folder containing ~20k mails needs some minutes, while kmail continuously rearranges the display. If I select all mails in the folder (pressing Ctrl+A) it takes about 5-6 minutes. I tried to apply filters on this selection (pressing Ctrl+J) and I had to kill Kmail after half of an hour running. Reproducible: Always Steps to Reproduce: 1. Create ~40 folders with corresponding mail selection rules 2. Download ~100k mails Actual Results: I had an older Debian system and I also tried it on a newly installed OpenSuSE system with the same result. I did not change the default settings. Expected Results: Some years ago I had similar system (on a significantly slower machine) having >300k mails and it worked with at most some seconds response time. Unfortunately I do not remember the versions. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
