Testing WAN performance

When testing WAN performance, node to node, what is the best way to test? I tried taking a file, making copies with different names, and putting one on each flash: of 3 different routers. I then did tftp transfers from the other 2 routers until I had tested each direction. I actually got WAY slower times than "xcopy" from a workstation (I am trying to eliminate firewalls from the issue).

Are there any other methods for measuring the WAN performance (other than ping, of course).

TIA,

Lee

Re: Testing WAN performance

Lee,

TFTP uses small packets and is not very efficient.

If your routers support it you can use TTCP (test TCP), which does a good job of filling the pipe. The command is hidden, so just try it. Enter TTCP, and if it is there you will be prompted for receive or transmit. Start TTCP on the receive side, then the transmit. The default settings work pretty well.
