[Digikam-users] Downloading JPEG is amazingly slow

[Gabriel Kerneis]

Hi,

I run Digikam 1.1.0 from Debian testing and I really enjoy using it,
except for the "downloading from a camera" part.

I shoot in RAW+JPEG and observe that downloading my RAW files (which are
bigger) is very fast, whereas Digikam seems to stall on every JPEG file,
performing whatever operation which makes it much slower. The resulting
speed (several seconds for every JPEG) makes it really unusable, and I
resort to using mv in command-line instead.

I first thought it was related to this bug [1] but disabling
autorotation leads no noticeable speedup.  The behavior is consistent
when I download directly from my D90 or when I use an SD-card reader.

As I understand it, Digikam must perform some operations on JPEG files
(inserting exif data into some database, maybe) which takes a lot of
time. It would be much better (IMHO) if there were a "quick download"
mode where those operations could be backgrounded AFTER the download has
completed (Digikam performing a mere "mv" and then running the usual
"new shot detection" stuff).  I am about to recommend Digikam to a close
relative, and already know I will have trouble explaining him why it
takes so much time to download his shots.

But maybe does this option exist already, and I missed it.  Do you have
any hint?
