Ask the customer to install Ethereal on the computer sending the file and
dump all data on the TCP session and send it to you, then use the Ethereal
function "speed over time" or what it's called.
It'll use the TCP information in the packet dump to determine over time
what speed the transfer was. If the speed is saw-toothing over time you
might have a very aggressive policer on the way which is hit by the faster
line, but not with the slower one.
