           Summary: Performance problems when sending (deleting) mail to
                    trash
           Product: kmail2
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: subscryer at gmail.com


Version:           unspecified (using KDE 4.7.0) 
OS:                Linux

As per the summary. Deleting a single message takes somewhere near 1-2 seconds
before the message is actually deleted from the message list and the list
itself has rearranged. If I press the del key a few times in a row without
waiting I get unpredictable behaviour often deleting messages without their
status changing to read as it used to.
Deleting a number of messages (a few hundred) takes easily a few minutes.

Related or not: if I open a folder with a substantial number of messages in it
(let's say near 1000 and up) it takes a few seconds for the message list to
stop populating/scrolling. In kmail1 this was fast enough that I barely
noticed.

I'm on a laptop with 4gb ram and a Pentium Dual-Core CPU T4300  @ 2.10GHz
I don't see substantial disc activity during deletes, akonadi backend is mysql
5.1.58.

Reproducible: Always

Steps to Reproduce:
I haven't tried on other systems but the behaviour on my pc is always
reproducible.


Expected Results:  
Wait times should be on par with kmail1.
