Description Johannes Obermayr 2013-03-27 21:25:02 UTC

Opening a message in kmail requires a lot of time after updating openSUSE 12.3 KDE:Unstable:SC from a ~ 2 months to a ~ 1 week old snapshot.

'top' shows kmail / akonadiserver / mysqld are using a lot of ressources even in idle trime:

Comment 1 Johannes Obermayr 2013-09-17 14:31:27 UTC

I had some time to debug:
- 4.10.5 from openSUSE:12.3:Update works
- 4.11.x and master didn't:
  - kmail's message window freezes after ~ 3 to 5 messages
  - akonadiconsole -> Browser is really fast and doesn't freeze

I found Bug 323740#c6. So I checked my system
~/.local/share/.local-mail.directory/.inbox.directory/
~/.local/share/.local-mail.directory/.Posteingang.directory/
(2nd was introduced by kmail-migrator [Bug 258926#c6])

moved all from localized .Posteingang.directory to default .inbox.directory and removed Posteingang (~ 30,000 emails via akonadiconsole -> Browser)

kmail is now really fast.

This sounds like it could be caused by Nepomuk feeder.

Anyway, it you see this problem again, please reopen the bug.
