Don't know how for RAW files but preview speed for JPEG files is
much slower...

Quality isn't so great.

1. What about 80% quality? Even when making size smaller. Smoothing of
   Qt is really good and personally I would prefer to see some Qt-blur
   instead of JPEG artefacts. (note: I use full screen Digikam in
   1152x864 resolution - on bigger screens it may look different).
2. What is sampling factor? In most systems 1x2 (or lower) is default
   but offers significantly reduced quality for modest size gains
   comparing to 1x1.
