Version: 1.13.0 (using 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1)) "release 212", KDE:KDE4:Factory:Desktop / openSUSE_11.2)
OS: Linux (i686) release 18.104.22.168-0.1-desktop
Sometimes when sending a mail, the virtuoso server goes to eat the whole CPU for 10-20 seconds.
During that time, kmail shows only the greyed out composer window and can not do anything else, e.g. I can not select a different mail.
I was hoping that decoupling many things into akonadi solves the problem with a blocking UI, but obviously there is still something borked.
The problem is that we are using a search job (search by email) synchronously, i.e. with exec(). Therefore the GUI blocks, we shouldn't use exec() in any place.
And of course Virtuoso should be faster in this case...
Problem confirmed. Kde 4.4.0 Gentoo AMD 64. Sending mail takes up to 30 seconds, high CPU use by virtuoso -t and nepomuk-services.
Should be fixed in KDE 4.4.1
