> With the current performance, the Tag-Feature is definitely not useable

> I am running DigiKam 3.0.0 under KDE 4.8.5 with the MySql-Backend. My
> Tag-Structure is complex, but not huge (maybe 30 Tags in different

> I had similar problems with DigiKam 2.8 - but less severe.

Please open a bug report about this.
- which process eats CPU, digikam or MySQL?
- do you perform any operation?
- how many pictures, order of magnitude, are shown in the view, are contained 
in your collection?
