I'm not posting this question in regards to a specific problem, but rather
something I've been continuously observing and don't understand.



When I copy files from one directory on a remote server to another, it can sometimes take a couple of second (around 10 to 20, I would estimate) for the files to "appear" in the directory it was copied to. What I mean with appear is that I don't see the file using ls until i've waited said time. I believe this happens regardless of file size/number. The server is not "unresponsive" due to overload or too much I/O.



What could be the reason for this?
