How long should digikam take to start first time with ~ 25k images?

[Chris Green]

I have a picture collection of somewhere around 25000 images (JPEGs
mostly).

I'm running digikam 4.2 on xubuntu version 14.10.  My system is a
quad-core Intel I5 based system with a fast SATA-III hard disk.

Digikam is taking *ages* to start up.  How long would one expect the
first start-up to take?

What do you mean by "First Time"  ??

The first scan time or just open digikam after a reboot?

For me just to open after a reboot it takes less than a minute.. and i have 17k of images.

For scan time i don't have a reference...

My images are in a normal 7200 RPM 2TB Sata driver.

Mine is as big as yours and take seconds. digiKam runs in a under powered Linux box using mysql. The collections are accessed under a gigabit network published via samba. It takes seconds under WiFi as well.

It has finished now but it took about 30 minutes.

That's not 'first time'.  I'm talking about the first time after
Digikam is installed and scans all images information into its database.

I guess 30 min to scan is not that bad.

Scanning progress at first run is very time consuming and run, for the
moment, only on one CPU core.

Process is this one :

Scan album
    Scan items in albums
        for each items, read metadata and register info to DB.

Read metadata is long and delegate to Exiv2 shared lib.
Register info to DB is long with SQlite.

In all case, i'm not sure if multicore will help here. Reading
metadata on more than one CPU will not increase speed, because of hard
drive speed limitation. If you use a SSD, it can be better of course.

Register info in DB, will introduce lock due to multiple access at the
same time.

My current solution is : Use a SSD to store at least the DB file.
Performance are really improved.

Better, use a SSD to store image. Here i use a 1Tb Samsung SSD.
Workflow become incredible. SSD price decrease each months. Don't
hesitate to switch from HDD to SSD.

Gilles,

There is a conf to sed the database file? 

Cause i have SSD only for my system, but i guess it would harm to have digikam database there as well.

All media is stored in a 2TB SATA righ now it includes the database.

Sorry typo...

Is there a option to set the database location?

I want only the actually database file in the ssd.

Unfortunately I can't access my PC, so I can't check..

If didn't understand just leave it..

In digiKam Setup dialog, Database page, there is the option that you need...
