First, a sanity check: 4 terabytes, divided by a good spinning-disk transfer rate of 100 megabytes per second, is ten hours at minimum. Easily 20 for more average disks. You'd need a fancy striped RAID array, or an implausibly large SSD, to beat that.
A great deal depends on your data of course, but knowing why trillions of teeny files are slower than fewer, larger files is not helpful in making the system access trillions of teeny files faster.
Generally speaking? cp does not have a "go faster" button, or else we'd be pushing it all the time anyway. cp is not slow, naive, or wasteful.
