- With PPP, I've noticed that "rsh" ( E.g.
- "rsh remotehost 'cat <filename' >filename", or whatever -- as long as
- it is a byte stream) is about twice as fast as "ftp" and "rcp". Is
- there a way around this? "rcp" and "ftp" are nice facilities,
- especially with wrappers like "ftptool".

- I don't get quite the same results, but I do see a small but
- significant speed advantage of rsh and ftp over rcp. I turned up
- debugging (I'm using Morning Star PPP, as you might guess :-), and
- noticed that rsh and ftp send full size frames (1500 bytes), but rcp
- sends 552-byte packets (552=20+20+512). Both sizes are before Van
- Jacobson TCP header compression.
