Followup - After regressing to 4.7.7R1, and then to 4.7.6R1, no change in sync time, still 1.5+ hours. It proved the problem is/was elsewhere, NOT HanDBase. I troubleshot my network and finally discovered the culprit was a new NIC I had installed a couple days earlier. A HanDBase sync was the only thing I had not done since installing the NIC. I removed it and sync times are now back to normal, 2-3 minutes.
I apologize for the erroneous problem report, but the timing did make me suspect HanDBase, since that was the last change.
