Read the top part of the text file. That sounds like it should help. It sort of gives priority to IO that needs it. While my OS is on a m.2 stick, the data that is giving me trouble is on spinning rust. It's those 50TB or so sets of drives. Usually I'm copying from one set to the other. I might add, there is also other data being accessed as well. Some of it reading, smaller amount writing, usually. It's torrent stuff on one set of drives. I added BFQ to the kernel config and rebuilt. I just need to reboot now. Watching a good show so I'll have to do that later. Open to other ideas as well. This may be enough but wouldn't mind adjusting other things that might make BFQ work even better or work along side it. Thanks much. Dale :-) :-) P. S. Still not sure on email thing. I want to but it sounds like a hair puller. :/
