The 'etherape' program will show you a graphic real-time display of
LAN usage.  Also, the 'mtr' command can help determine a bottleneck
outside of your LAN.

I think there's a bug int he etherape package - if you run it from the
menu it cannot open any interaces.  You have to either run it via sudo
in a terminal (sudo etherape), or edit the menu item and make the
command 'gksudo etherape' instead of just 'etherape'.

HTH,
