Please comment below on the average per-image time it’s taking your library to upgrade. Be as detailed as you can; for example my hardware is:
MacBook Pro 15” 2.93GHz 4GB RAM
• Original import of A2 library to an A3 library took about 3 seconds per image
• ”Processing” took 3 seconds per image (although it bizarrely seems to have skipped 10,000 images for processing; see my February 14, 2010 at 11:09 AM update here.
• ”Faces” took 6 seconds per image
