In this example, the Ping command sent four packets of data to the IP address associated with and received all four packets back without any loss. Minimum = 9ms, Maximum = 12ms, Average = 10ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: Here is a an example of what the results of the Ping Command might look like: Pinging with 32 bytes of data: Repeat the test several times over a period of minutes or hours with multiple sites and devices to get a more accurate picture of network latency over time. If the RTT is high (over 100 ms) or fluctuates significantly, you may have latency issues that require further investigation. If the RTT is consistently low (less than 50 ms), your network latency is likely performing well. You will see the results of each ping attempt in the Command Prompt or Terminal window, including the round-trip time (RTT) in milliseconds.Īnalyze the results of the ping test. The command will send several packets of data to the target device (in this case, the Google website) and test the time it takes for the responses to be received. Type ping followed by the IP address or hostname of the device you want to test. Open a Command Prompt or Terminal window on your computer. Here is an example of using the Ping command to test network latency: You can verify this on multiple devices and scenarios in your network This can be a quick and easy way to get a basic measurement of network latency. If your internet speed is consistently poor, speed tests might reveal a more pressing issue with cabling or equipment that needs to be fixed.Ping is a simple command-line utility that sends a small packet of data to a specific IP address and tests the time it takes for the response to be received. It doesn’t matter whether you’re paying for 100Mbps or 1Gbps if you’re only getting half of what you pay for at any given time, then you might as well save some money and drop to a cheaper tier. Internet service providers sell packages at various speeds, so it’s worth making sure you’re hitting those speeds to justify the cost. The main reason is to find out whether you’re getting the performance you pay for. There are some good reasons to test your internet speed periodically. It’s up to you how you interpret your results: is your “real” speed the speed you get in the day when you and everyone else are working? Or would you rather know the theoretical maximum, when most people are tucked up in bed? Your ISP would certainly pick the latter. I’ve seen results that drop as low as the 200Mbps range in the day, while nighttime performance consistently hits the 1Gbps barrier. CloudFlare’s speed testing tool shows far more information and repeats the test several times, plotting your results on a graph. For example, simply shows your download speed until you opt to see more (where you get your upload speed and latency). Some services are vague in their reporting. Distance seems to affect the reported speed, so you might find that servers closer to home report faster speeds (and certainly lower latency). Some might not even have a server within hundreds of miles of your location.īecause there are so many variables involved, different services will give you different results. Some speed test services let you choose a server, others give you no choice. You will encounter some variability when running different tests on the same service, particularly for providers like which use different servers depending on where you are. Your internet service provider might even have its own speed test service. There are plenty of internet speed test services to choose from, with, , and CloudFlare being some of the most well-known options. So how can you know for sure, and does it matter? Different Speed Tests Report Different Results Do you know how fast your internet connection is? Depending on which service you use, you could get vastly different results.
