"Speedometer shows a graph of your current and past network
speed in your console, letting you see your network connection's up
and downstream speed and history at a glance. You can also use
speedometer directly on a file to monitor the download performance
and history of a specific download instead of all network traffic.
When displaying the total network traffic, speedometer is sort of
like gkrellm, in that you can see the current and past network
performance on a graph, but you can easily run it over an SSH
connection without having to set up gkrellmd.
"Speedometer is packaged for Ubuntu Hardy and as a 1-Click

a 64-bit Fedora 8 machine..."
