Just to close this off - I used real-debrid only for about 10 days ie no direct downloads from Filefactory.com. A few days ago, it appears the problem has gone away. All direct downloads are back to normal speeds again. Nothing changed from my side. No response from Filefactory.com to my trouble ticket.
I guess I will never know.
