Hi there,

I was updating digiKam yesterday to V. 2.6. Nice impression, congratulations!

Starting procedure is extremely slow- similar to previous v. 2.5.

Some data from "help >> statistics of database":

Starting digiKam at..,.

Time              Durance        Memory
19:11:24           00:00:00
19:18:05        00:06:41       2681292
19:28:00        00:16:36       3027132
19:33:35        00:22:11       3660744

So, after some 23(!!) minutes, digikam starts up finally.

Astonishing observation for me: it looks like only _one_ of four cpus were
engaged- value constantly nearby to 25%. Somestimes, CPUs changed.

File sizes: 
thumbnails-digikam.db: 4,7 GB
digikam4.db:                  350,4 MiB

Hope this indicates you potential for improvements.


Axel
