Re: [KPhotoAlbum] Re: New snapshot (was : date + setup + help missing + database)

[Dominik Stadler]

Hi Jesper, 

I tried to play around with the latest and greatest KPhotoAlbum and used
valgrind to start the demo-database (it seems to be unable to cope with my
real database, with over 10500 images it consumes more and more memory
during startup until I kill it). 

It seems during startup, KPhotoAlbum periodically loads and unloads a bunch
of libraries, it seems this is done once for every image. Valgrind prints
the following frequently until the main UI appears:

Also when selecting all images from a category, this output appears once.
I'm not sure how big the cost is for loading/unloading a lib, but if done
very frequently, it might add up.

The same when I import an existing .kim-file.
