Created attachment 109519 [details] RAM comparison - open a folder in the Windows explorer and show it with small thumbnails - now start digiKam and open the same folder as image preview - now compare the RAM usage result: while the Win explorer needs only 33 MB RAM for the image preview, digiKam needs more than 100 MB more, see the attached screenshots. This is quite a lot for the same action.

Digikam is not a file browser but a photo management suite, meaning it has much more features and tracks much more information about items (photos, ...) than the native file manager. You are comparing apples with oranges here...
> it has much more features I understand this. I was only wondering that digiKam uses so much more RAM despite I did nothing else than opening it. I did not start any map, I even didn't select an image or edited one. Therefore I assumed that there is room for improvements.
Not reproducible with 7.0.0-beta1
