Import speed, is it really that slow?

Hi everyone,

since I got a new Camera I looked around which kind of Software I
could use to manage my Photos. digiKam looks like it fits very well,
so I gave it a shot (or two in this case).

First, I installed it in a VM just to play around with it a little
bit. To get some Photos into digiKam I used the "Import from foreign
PC / location". I did this for 47 Photos (Jpeg, ~6MB each) and it took
20 minutes. I thought it´s because it runs in a VM which can make some
things much slower.

After a while I installed it native on my PC (Windows 7 x64, Core
i5@4.5GHz and 4 GB RAM) and did an import for the same 47 pictures.
This time it took 17 minutes. While the Import process was running
there was no considerable CPU activity (3-15%, so not even 1 core
running full), no noticable HDD activity and no Network traffic (this
time I advised digiKam to save the pictures on my NAS).

Also while the Import process was running that slow, digiKam sometimes
did not react to my Input. What I mean is, that when a process hangs
you cannot click into the Window. It seems like digiKam grabbed one
pic and just sitted there and did nothing for a while and then grabbed
the next picture.

Since it´s my first day with digiKam I´m probably doing something
wrong. Can someone help me here or is the import process really that
slow? If yes, I think I need a long holiday to import my hundreds of
pictures.

Regards,

buedi

As an addition to my intial Post:
On Import and on other activities within digiKam the Application
sometimes does not respond. It seems to go to lunch for 10-15 seconds
sometimes. I used the Installer from Sourceforge (I did not install
KDE 4 Win manually). Maybe something´s fishy with the KDE 4 Win
environment causing these lock ups? It seems like this is also the
reason why the Import takes so long.

Re: Import speed, is it really that slow?

Assuming you have reasonable hardware, something is wrong with the install.
At least when compared to a native Linux install (SuSE 11.4 in my case).
I do not have DK on Windows experiencefor comparison.

While here, I will also observe that when importing from SD cards, USB
is a significant contributor to normal delay.
I'll estimate that USB3 with a USB3 reader is 2x plus(faster) over same
card in a USB2 setup.

Hi Carl,

thanks for your reply, I appreciate that very much.
I don´t think it makes sense that you make a test with the import
picture functionality. Further testing yesterday and today revealed
that I have these freezes all the time in Digicam and its included
tools (Lighttable and Picture Editor). The whole Suite freezes for
10-15 seconds, sometimes several times in a minute (which makes you
more waiting than working) and sometimes you can work for a few
minutes and then *boom* freeze again.

I did further testing on a XP SP3 x86 and my Windows 7 x64 System. On
both I tried the digiKam 2.2.0, 2.3.0 and 2.5.0 packages. I used the
internal SQLite Database and a MySQL Database stored on my NAS. I
worked with pictures from an USB stick, my local drive and on my NAS.

The freezes are independent from the setups / variants mentioned
above. Since while the App is frozen I can see no CPU and HDD activity
I don´t know how to "debug" this. I can´t be the only Windows User
here and I wonder what setup others use and how it works for them.

Kind regards

I did some more testing and it seems like the hiccups / freezes have
something to do with kioslave.exe. I cannot prove it because I do not
know if there are any Logfiles. I don´t know if filing a Bug report is
OK with the lack of information I have. Maybe someone can point me to
the right direction, so I can provide a Developer the necessary
Information to look at that? It would be a shame if someone puts so
much effort into a Windows Version of digiKam and nobody is caring if
it´s working or not. I do, because I think it´s a remarkable piece of
Software.

It also seems like I have no hiccups / freezes when I do not touch the
Import function. If I only work with other digiKam functions
(Lighttable, tagging, searching...) yesterday I had no freeze at all.
As soon as I touch the Import function it starts to freeze after
importing 3-5 pictures and the Import process takes ages. Also after
the Import Process, digiKam freezes again and again until I close it
properly and open it again.

Yesterday once the kioslave.exe caused an exception while digiKam was
freezing again. Having a look at the Taskmanager revealed around 5
kioslave.exe processes. On my XP System when I do the Import it opens
around 10-14 of these processes. Maybe there´s a problem with that
process and not digiKam itself. DigiKam may be waiting for the
kioslave.exe to be finished maybe?

Back when I ran digikam on Windows, I too had issues that seemed to be
related to kioslave. Unfortunately kioslave is part of KDE 4 Windows and
so it is not clear where the problems really lie, in the KDE 4 Windows
port or in the digikam slave code.

Your best bet may be to simply copy the photos into your album directory
structure without using digikam's import.

In order to get debug output you need DebugView
http://technet.microsoft.com/en-us/sysinternals/bb896647

and then

"Run kdebugdialog from digiKam install path. It must be an executable
file. It show a dialog with all debug space to display in debugview.
Turn on digiKam, kipi, kdcraw, kexiv2 space, run debugview, and
digiKam..."

By all means file a bug, it should all help in getting attention for
these things, but it may take quite a while.
