Even the endpoints are likely operating at different speeds - my fixed systems
(including the BBSs) run at 100Mbps on the LAN, and my Internet speed is 100M
down, 40 up.  Each user will be running at different speeds, and on top of
that, each path has an effective throughput that varies, depending on the path
packets take and the amount of traffic at the time.  It's quite instructive to
do an Internet speed test at a server on the other side of the world.  Ahile I
may get up to 80 Mbps from the nearest servers, I only get 3-5Mbps from servers
in continental Europe.

So, that's a long winded way of backing up your comment DM. D
