--- Comment #5 from DrSlony <bugs@londonlight.org> ---
Hello

4.10.0 is an improvement but it still has no option to show the full-sized raw,
and the half-sized raw uses auto-levels adjustment which is bad for people who
want to see the real raw file but I already opened an issue for that. The
half-sized raw option is also quite slow, takes about 2-3 seconds here. Maybe
you can use RawTherapee's optimized code
https://code.google.com/p/rawtherapee/source/browse/rtengine/amaze_demosaic_RT.cc
but I don't know what the bottleneck is - maybe it's digiKam's demosaicing, but
maybe its not. It could be LCMS or some other operations. A digiKam developer
would need to insert timers and test.
