Network Latency

Hi, there. How would you measure network or internet speed or so-called network latency?  The higher latency the slower speed you may suffer. Ping and Tracert command in windows can be used to execute the measurement.

In network normally if the PC from longer distance, theoritically it would give higher latency. Eg
 Ping -l 65500 pc-001  then it would shows average round trip  17ms   (Longer distance)
 Ping -l 65500 pc-002  then it would shows average round trip  15ms   (Shorter distance)

above command is to send 65500 bytes from source to destination then vice-versa.
A good latency should be below 20ms under 65500 bytes in travelling.

In internet normally if the website from longer distance, theoritically it would give higher latency as well.
Ping -l 0 www.dropbox.com then it would shows average round trip 292ms
Ping -l 0 www.google.com then it would shows average round trip 14ms

A good latency should be below 1000ms under 0 bytes in travelling.

Hope it helps..
