That sounds bad. How did you tag the images? By selecting the tag in the tagging module and clicking the "attach" button, or using the quick tag feature (ctrl-t, type, enter)? Could you please try the latter if you didn't do so before and tell me if that's faster? > By way of comparison, I accessed a copy of the database file directly and > used an INSERT INTO command to apply the same tag to the same images.
