Summary: Just upgraded from kmail to kmail2, kmail2 is dead
slow, uses a lot of CPU and 2Gb of mem
Product: kmail2
Version: 4.7
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general

Hi
First of all I just want to state that I have been a very happy kmail user for
many many years. For a long time kmail has been sinply the best email klient,
(IMHO)
However, I just upgraded to kubuntu 11.10, and then kmail was upgraded to
kmail2 too.
Now I am not so happy anymore....
I am sure accessing the maildirs via this akonadi thingy is a good idea if you
have a couple of hundred emails in total. If you have approx 400 000 and 6Gb it
is not....
Just checking email ( and there are like 10 emails on the pop3 server) takes
now at least 2 minutes, and during those 2 minutes the CPU load goes sky high.
("Syncing collection xxxxx" is what I think kmail is doing that takes so long.)
Then, reading emails is of course also dead slow, but that is already reported:
Bug 277770 - KMail2 is slow when accessing messages in folder
I do in particular have one folder were there are 160 000 emails (subscribe to
a few high traffic mailing lists for some years and you are there). This is the
folder that causes most problems for kmail2 (also when checking email and
there are no emails that is supposed to be filtered to that folder ).
So, is there way (or a plan ) for making it possible to let kmail access the
maildirs directly so that kmail becomes usable again? or in some other way fix
the performance bottleneck the new architecture obvious is ?
Best regards,
Vidar
Reproducible: Always
Steps to Reproduce:
Load kmail with 100 000 emails and see the performance, or the lack of it
Expected Results:
kmail2 should have similar performance as kmail and be possible to use even
though you have many emails....
