Slowness of NEF:

I did not really take care where exactly it was slow, it was just taking
ages on my atom netbook computer.

>From my experience, it takes too much time to generate the preview
images, which is typical to ufraw. Since F-Spot was not working well, I
used my own scripts to copy and convert, and I found that by far the
fastest (and best!) way to generate previews or fast examples is to
extract the embedded preview jpeg. My Nikon D300s embeds a JPEG in full
size (no idea at the moment whether it does this by default or whether
there is a configuration setting to choose) into the NEF, which can be
extracted extremely fast and shows the picture exactly the way the
camera has intended. Only disadvantage is that this jpeg lacks the exif
and other data.

You cound accelerate shotwell extremely if you try to extract the
embedded preview jpeg, if it exists and is large enough, and convert the
raw otherwise.
