Hello All:
One Semi-Solution I have found is that the ND files in the QuickBooks data folder becoming enormously large. This by my experience and not by the Tech Support's advice has been the contributor of the slowness of the banking rules and their creations.
If you perform regular backups of the data in QuickBooks, this file will be reduced in size therefore improving the performance of the Rules Creation in QuickBooks.
Please try it and see if my experience applies to your situation.
Sincerely,
AlcompCo
