Hi Guy

ALL machines on hub A and B (which I have been looking at) are running at 100Mbit/s (or so the status of the network card says)

and yes as far as i can tell (amongst all the wiring) the switch is connecting together about 5 hubs 

Cheers

HTTP packets are almost certainly TCP packets.

So the network adapter on machine B plugged into hub B is running at 100 
Mbit/s, as per

Is the network adapter on machine A, plugged into machine A, also 
running at 100 Mbit/s?

What about the network adapters of the other machines plugged into hub B?

And where is the switch in this network?  Is it used to...

...connect the two hubs?
