If you have ever pressed Ctrl-Shift-1 to reveal the Viewer Statistics panel and wondered what all the stuff means, there is a good explanation of the items in the panel over at the Firestorm Viewer Wiki. See: Firestorm Viewer Statistics. Almost the same information is available in the SL Wiki: Viewer help: Statistics.

I think on both sites they have simplified the text for the less techy users. I think that is a bad idea, as the people looking for explanations of how the items in the panel work are likely tech savvy.
The first four items listed on the pages are the source of a lot of confusion; FPS, Bandwidth, Lost Packets, and Ping. So, I’ll provide a bit more information.
