About one order of magnitude slower, and a great deal more cpu time.
But that's not the problem I have with ssh vs rsh, it's copying large files.
Just last week I needed to copy 65GB of data from an ext3 formatted IDE
harddrive someone brought in. The only linux system that I could bring down
to stick the drive in was my VIA-C3 based thin-client. Using scp to copy the
files would have taken all day. If I could just turn off the stream
encryption when I don't need it, everything would be fine. Too bad the
security-nazis removed that option.
