Digikam needs about 10 minutes to start

[tuk37]

Hi

Digikam starts very slowly (about 10 minutes) without producing any
error messages. I deleted digikam4.db but it did not change anything.
"top" shows 10% system load (caused by digikam).

What can I do to make digikam start faster?

My system: Laptop with Intel core i5, ext4, 2GB RAM, Kubuntu 11.10

Thanks

Hello,

   How big is your image collection?  When you looked at "top" did you
see a lot of "wa"?  Can you also run "iostat -m 10" when you start
Digikam to see if there is a lot of activity on the disk?  What kind of
hard-drive are you using (5400RPM, 7200RPM, SSD)?  On what kind of file
system is your image collection stored?

Personaly, I have over 30K images in my collection on a Intel Core 2Duo
with 3GM RAM and a 500GB 7200RPM HD and Digikam starts in a few seconds.

Cheers,

Samuel

My collection: more than 30k images in more than 1k subdirectories with
more than 60GB.
FS is ext4. Hardware: No SSD, "HITACHI HTS72503" - I think it's 7200RPM.

I have the same problem. Digikam needs a lot of time checking for new
pictures. If I switch this off in preferences (not looking for new
pictures), it's starting quite fast.
I am not very happy with that, as checking for new pictures is actually
neccesary, if you directly put any pictures in your collection folder.
Otherwise they dont appear in your collection. After doing this I let
digikam restart for the search and afterwards switch that feature off again.
If I have connected all external collections it takes 5 to 10 minutes as
well.

If/when you know you've new pictures, you can use "Refresh" from the Menu, and I think it also works for the album and sub-albums selected, so it's quicker than do it for the whole collection.

Until now I used dolphin.
