So the user is reporting that revealing passwords is fast now after the upgrade. I guess I misunderstood their issue. They are now saying that opening an individual password entry (not a list) to edit it is what was taking 12 seconds. I had them only show 20 entries on the list and it cut the time down to about 5 seconds. I had them check on a list with fewer than 10 entries and it took about 2.5 seconds to pull up the edit screen.
