There's not much to explain about the numbers in the connections view. You see the number of messages routed through the connections (in and out), the bandwidth usage and the percentage of dropped messages.

You cannot interpret that data without at least basic knowledge of how gnutella works. - Many routed messages can mean that a the remote host is very well connected but it can also mean, that it is connected to clients spamming the network with requeries. The bandwidth usage is usually proportional to the number of messages routed and the percentage of dropped messages is hard to explain if you don't know how messages are routed and what messages are filtered by LimeWire.
