Hi,

What do you mean by "Slow to write XMP" ? For using NEF only and at the  
beginning, when XMP didn't exist yet, I'm used to write metadata in the  
RAW file, and I can say it takes still more time than writing XMP.

What you have to keep in mind, is it take a long time the first time you  
do this, but after that, when RAW files get their XMP sync with Digikam  
Database, it should be almost like before when you use JPEG for metadata.

Regards,
Nicolas
