That's a good possibility. Your test could easily be corrupted on either side - the send-from-disk could have been thrown off by the OS caching the files in RAM and the send-from-RAM could be thrown off if the ramfs had been swapped out. Linux uses both caching and virtual memory pretty aggressively. OTOH, as a previous poster suggested, it seems more likely that your hard disk is just faster than your network connection, in which case I would expect to get the same results either way. > Question: Can I tweak scp or use something else to send files directly from > RAM of one computer into another as fast as possible ? Why does it need to come out of RAM? Make it up on the fly - pipe /dev/urandom or the output of `while /bin/true ; do echo 0 ; done` across the network and you don't have to worry about the data being cached. -- When we reduce our own liberties to stop terrorism, the terrorists have already won. - reverius
