--- Comment #26 from Peter Albrecht <px79 at crazymonkeys.de> ---
I did some more testing: Tiling is definitely a problem with colormanagement on
my machine.

I changed
"digikam-3.5.0/core/utilities/imageeditor/q3support/previewwidget.cpp" line 65
from
     tileSize(128), zoomMultiplier(1.2)
to
     tileSize(1280), zoomMultiplier(1.2)
This effectively disables tiling, since all image fits in one tile.

I compiled this source and now tool starting in Image Editor is as fast as
before (about 1 second).

So I have found a first personal workaround. ;)
But, of course we/I should investigate further. It must have a reason, why
tiling was introduced first.

What bothers me, too, is that this bug can't be reproduced by you, Gilles and
Andreas. Are your CPUs that more powerful than mine? I use a "Intel(R)
Core(TM)2 Duo CPU, E8400 @ 3.00GHz".
