Yes, though I only have 4438 items in DEVONthink To Go at this time. Should that make a difference? Perhaps, perhaps not. As I said, I don’t know how the underlying mechanism works. However, parsing a specific UUID out of a dataset of 147,000+ items would logically take longer than 4,400. A minute or more? Could be it’s just using a lot of memory locating the item.
Is it still slow after rebooting?
