[AccessD] OT: Network speeds

I have a network which consists of a set of three gigabit switches.  When I transfer files between 
servers at either end I get 11 MByte / second transfer speeds.

NOT good!

Unfortunately I don't know how to troubleshoot this.  I have simple a cable tester and the cables 
test OK, although that is truly only a connectivity test, not a test of the quality of the signal.

I used to have a little program, a server on one end and a client on the other.  The server would 
send stuff and then you could run the client on any other computer and see the network "quality" at 
the client end, wherever that might be.

I can't remember what the program is and I am looking for something quick and easy.  Of course 
nowadays everyone wants to test internet stuff.

Does anyone know of a simple client / server kind of thing that allows me to install the server on 
one end and the client on my laptop and just walk around connecting my laptop to switches to try and 
determine where my problem might be?
