While investigating a VPN problem, I ran "ping" from a Windows2000 box
across a lossy link which crosses the Pacific Ocean 4 times to get the
response back to me.
Ping statistics for xx.xx.xx.xx:
Packets: Sent = 120, Received = 99, Lost = 21 (17% loss),
Approximate round trip times in milli-seconds:
Minimum = 550ms, Maximum = 691ms, Average = 468ms
So, the average time for those packets is significantly less than the
minimum time, eh? They've clearly divided the total time for successful
replies by the number of total packets *sent*, not *received*. Smart, huh?
It certainly looks like that Windows ping command is much more efficient
than the competition!
Greg.
