           Summary: Very slow commit after tag change only in digikams
                    image editor
           Product: digikam
           Version: 1.2.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: krienke at uni-koblenz.de


Version:           1.2.0 (using KDE 4.4.3)
OS:                Linux
Installed from:    openSUSE RPMs

I run digikam 1.2.0 on a Core Duo 3GHZ system with 4GB RAM using openSuSE 11.2
with KDE 4.4.3 . I have about 11000 photos I manage using digikam. 

Recently I added one new tag to a photo which has about 30 tags assigned which
are also stored in the file itself. After checking the tag name in the right
sidebar I clicked page up, to get to the next photo and nothing seemed to
happen.  I can then see that one CPU core goes up to 100% and it takes about
10sec until the cursors changes to the busy shape and then some more seconds
until the next photo is shown. During those 10sec digikam does not respond to
any input, mouse clicks or whatever. The share Metadata to Nepomuk is not
activated in digikam and in KDE I disabled Nepomuk-Strigi file indexer for this
experiment.

This seems to  happen always with no matter what photo I try using imageeditor.
If I do the same in digikams main window in its right side bar it takes about 2
or 3 sec until digikam is responsive again after appying the tag change. 

I think 10sec to apply one additional tag is quite a lot and it really makes
walking through photos and setting tags a pain. Moreover its striking that I
have to wait 10sec only if I set the tag in imge editor else its takes only 3
sec for the same task.

Thanks
Rainer Krienke
