On the serious side:
I have never heard any good explanation of this behaviour. The copy function knows how many files it must open for read, how many for write - presumably the same number, but the time required for preparing write operations could be different from read. In any case, the time is roughly the same for every file on a given disk. To open the file, the MFD entry ("inode", for you *nix guys) is inspected. It also tells about the size of each file, so you roughly know how many pages will be read from or written to the disk - at least you know the difference between kB, MB and GB size files. You have a rough idea about the transfer speed, based on the disk technology. If you don't, after opening a couple of files, that will tell you the time overhead per file. After you have copied a few megabytes, you roughly know the transfer speed.

I am certainly not expecting a three decimals correct figure. I just cannot fathom how it can jump up and down by magnitudes, even after the copy operation has been running for a while, with empirical figures right at your fingertips.

If anyone knows why, I'd like to know, too!
