Why do some programs have higher TCP latency periods than other programs?

Why do some programs have higher TCP latency periods than other programs?

See the latency column under TCP connections.

In addition, why does process ID 2272 have more activity (in terms of B/sec sent) under "Processes with Network Activity" than under "Network Activity"?

Answer 1

Latency means delay. All connections to different hosts are going to have different latencies; that's pretty normal. Also, measured latency typically varies even to a given host as network paths and traffic affect delivery time. It is possible that TCP latency means something special in this case, but I don't know what that would be.

If you look further down under "Network Activity", you'll see process ID 2272 listed again, with a connection to a second host. If you sum all of the connections for process 2272, I suspect you will get the total under "Processes with Network activity".
