Hmmm without being a maintainer. I would say cp -r is most used on single disk, so one thread is using the maximum disk iops taking y time to copy. What would solve using multiple threads each taking their share of the maximum disk iops, and because of the scheduling and other overhead finishing later than y time?

If it’s something that’s possible, are there any plans in making a multi-threaded cp? I’m not a member of the list so I kindly request you cc me on the reply. Thank you.
