--- Comment #33 from Martin Steigerwald <mar...@lichtvoll.de> --- David, to me this appears an issue that is not directly related to folder synchronisation speed although slow folder synchronisation speeds makes it worse. I think it is a mixture of Bug 367892 - During folder synchronisation Akonadi blocks out other operations like deleting or viewing mails and probably needless folder synchronisations. I reported IMHO needless folder synchronisations for maildir already in: [Akonadi] [Bug 334209] New: synchronizes folder contents with filesystem on switching folders needlessly For IMAP I reported something similar in Bug 367892 mentioned above. Hitting delete key to delete messages from IMAP folder here easily triggered a folder synchronisation (what for?). I think this is also a candidate for a separate bug report. For IMAP servers these folder synchronisations are likely required as other clients can update the IMAP account behind Akonadi. Yet, KMail should not block on these. Please try to separate different issues. I bet what would help you most would be that Akonadi does not block on folder synchronisations. So I suggest you add your finding there. Unfortunately there are quite a bunch of performance related issues still left in Akonadi. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.
