--- Comment #25 from Martin Steigerwald <mar...@lichtvoll.de> --- Okay, I seriously don´t get why its so different for you: One folder with about 10000 mails about one second with cold caches and one with more than 24000 mails about 2-3 seconds with cold caches. This time on Dovecot based IMAP. Regular IMAP, not disconnected. You do have double the amount of mails than the larger one of my folders, Gunther, but opening your sent folder takes about 30-40 times longer than on my system. So there is hope to fix your issue, I think, once it is clear what is causing the high load on your system. I wonder how to find whats different tough. Care to share more details of your setup? Also… do you have any search folders that target mails of your sent folder? My IMAP account setup is very basic. I just pointed it to my Dovecot IMAP, and then let it autodetect the encryption. Thats it. No customizations so far. So what you could try would be: Use a *new* user, recreate IMAP account from scratch. And try then. Also are there any errors Akonadi shows in ~/.xsession-errors or Akonadi error log. Are there any errors in MySQL log? Okay, just reading your mid air collision comment as well: So you have local IMAP, that should be even faster. I also tried clicking folder and then clicking mails. Its just instant with warm caches, i.e. folder already opened before. Okay, and even with cold caches, after the initial delay of 1-3 seconds and maybe an added second its instant. I click mail and its done. IMAP resource doesn´t synchronize the folder on my setup when clicking mails in a folder that it synchronized initially after starting it. What I know is that it does when deleting mail and this can cause quite some slow downs, but not when reading mails. So are you doing any other changes to the mail other than KMail setting read flag on them? I can reproduce huge delays when entering inbox for example and then hit delete 10-20 times. But but its not that MySQL heavy. It is just that Akonadi IMAP for some reason resynchronizes folder content after deleting a mail. So I think that is a different issue. Okay, will post about query logs in next comment. -- You are receiving this mail because: You are watching all bug changes.
