Count your hops. Holding network speed constant, each hop increases the transit time by a multiple.
Let x = rated network speed. One hop = X/1 Two hops = X/2 Three hops = X/3 And so on. In other words: consider a packet traveling directly from point A to point C. It arrives at point C at network speed. Now insert point B. The packet arrives at B in the same elapsed time as before, but must traverse the network again to arrive at C. Hence, the elapsed transit time is doubled. Of course, it is a bit more complicated but you should get the idea. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of François Paré Sent: Friday, June 20, 2008 8:06 AM To: [email protected] Subject: Re: Slow FTP transfer from z/OS to Unix Rob, We tried TRACERTE but there is no problem there, one hop a couple of milliseconds.
