Have you ever made Nautilus copy/move a huge directory tree and then
started a similar task for other directories while Nautilus was still
working on the first task?
A directory containing 10,000 1MiB files moved to another directory
completes immediately. Copying takes a while, as expected, and multiple
copies has the behavior you describe.
An SSD drive might not have this problem, but a spinning disk definitely
will. You should never try running multiple copies on the same disk if
you want it to finish in a reasonable time. With one copy, you can do
long contiguous reads and writes, but if you have multiple copies
happening, the read and write head will be bouncing all over the disk.
