Version: 2.0.89 (using KDE 4.5.95) OS: Linux It's difficult to quantify the performance difference, but from a user experience perspective KMail 2 is sluggish when accessing IMAP servers. As an example, the same machine running Kontact 4.4.9 delivers nearly instantaneous interaction when switching between emails that have already been cached while the KMail 2 has a perceptible lag in the same situation. I have set the severity as higher than normal because this issue will impede adoption among business users. Reproducible: Always
I can confirm this behavior on kde 4.5.95 and Archlinux. The performance of kmail2 with akonadi backend is poorer compared to kmail(1), as far as I can tell, for a longer time (since 4.6beta2). For me, opening a folder with 1000+ emails takes some time (didn't ever happen with previous kmail), I can see a 'waiting circle'. Also, mysqld kicks in and takes quite a lot of cpu at the time. I should say I'm running a netbook, but as said before, with older kmail it's ok. Thanks a lot and I hope this can be fixed.
Hej, can you retest with a most recent version of KMail2, please? We did many performance improvements lately. The IMAP access itself is _much_ faster then in KMail1, only the UI had been slow. Ciao, Tobias
well, sorry to respond late. Finaly I am on kde 4.6.4, kmail 2.1.0 so I can compare. pros: - fetching messages to akonadi resources seems faster or same speed. - acting on a loaded message list is considerably faster! I mean like scrolling the list, opening folded threads, displaying a msg after selecting it in msg list is now almost instat ! Great work here. cons: - one thing is (still) considerably slow and annoying, opening and displaying the message list after selecting a folder with the mails. On a folder with cca 3k mails this takes 2-3s on my atom, a folder with >22k mails takes 22s! :( I tried both settings in Appearance>Mailing list>Configure>Advanced: Favor interactivity/speed. With no speed gain. Thank you, Mark
...sorrry, not 22s but 12s for 22k+ mails in a folder.
