In today's fast-paced business environment, reliable and efficient network connectivity is crucial to the success of any organization. Slow or inconsistent connections can disrupt operations, cause delays, and negatively impact productivity. One of the key factors that can affect the performance of your network is latency, or the delay between the sending and receiving of data.
By testing your network latency, you can identify potential issues and take steps to optimize your connection for maximum speed and reliability. In this article, we will provide a comprehensive guide to testing your network latency, including recommended tools and techniques.
Whether you are an IT professional, a small business owner, or a member of a larger organization, this article will equip you with the knowledge you need to ensure a smooth and efficient connection.
Network latency is the time it takes for data to travel from a source to a destination and back again. It is often referred to as the "delay" in a network and is typically measured in milliseconds (ms). Latency is an essential metric in network performance because it affects how quickly devices communicate and respond to one another.
For example:
- When you click on a link, latency determines how fast the website loads.
- In video calls or online gaming, latency influences how smoothly interactions occur without lag or delay.
- One-Way Latency: The time it takes for a packet to travel in one direction (e.g., from your computer to a server).
- Round-Trip Time (RTT): The total time for a packet to go to its destination and back, often measured using tools like ping.
We asked a supercomputer “What is latency”, its impact on network performance, and strategies for minimizing it and created this comprehensive guide.

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. This can be a quick and easy way to get a basic measurement of network latency.
Or a simple https://www.speedtest.net/ can do the work for that. You can verify this on multiple devices and scenarios in your network
here is an example of using the Ping command to test network latency:
Open a Command Prompt or Terminal window on your computer.
Type ping
followed by the IP address or hostname of the device you want to test. For example:
ping www.google.com
Press Enter.
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. You will see the results of each ping attempt in the Command Prompt or Terminal window, including the round-trip time (RTT) in milliseconds.
Analyze the results of the ping test. If the RTT is consistently low (less than 50 ms), your network latency is likely performing well. If the RTT is high (over 100 ms) or fluctuates significantly, you may have latency issues that require further investigation.
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.
Here is a an example of what the results of the Ping Command might look like:
Pinging www.google.com [216.58.194.196] with 32 bytes of data:
Reply from 216.58.194.196: bytes=32 time=11ms TTL=118
Reply from 216.58.194.196: bytes=32 time=12ms TTL=118
Reply from 216.58.194.196: bytes=32 time=10ms TTL=118
Reply from 216.58.194.196: bytes=32 time=9ms TTL=118
Ping statistics for 216.58.194.196:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 9ms, Maximum = 12ms, Average = 10ms
In this example, the Ping command sent four packets of data to the IP address associated with www.google.com and received all four packets back without any loss. The "time" value for each packet represents the round-trip time in milliseconds, or the amount of time it took for the packet to travel from the computer to the Google server and back.
The Ping statistics at the bottom of the output show that the minimum, maximum, and average round-trip times were 9ms, 12ms, and 10ms, respectively.
Here are some scenarios using ping to troubleshoot network latency (the following commands are different on mac and linux):
Ping the Local Host: Start by pinging the local host to ensure that your computer is functioning correctly. Type ping localhost
in the command prompt or terminal to check if the response time is within an acceptable range. If the response time is high, it could indicate an issue with your computer's network adapter or other hardware problems.
Ping the Default Gateway: Ping the default gateway to verify that your computer can communicate with the local network. Type ping <default gateway IP address>
in the command prompt or terminal. If the response time is high or there are lost packets, it could indicate issues with the local network or router.
Ping a Remote Host: Ping a remote host on the internet to check if latency issues are due to the network infrastructure or the remote host. Type ping <remote host IP address>
in the command prompt or terminal. If the response time is high or there are lost packets, it could indicate issues with the remote host or the network infrastructure.
Ping Traceroute: Use the ping command with the -T
flag to perform a traceroute and identify the specific point where latency is occurring.
Type ping -T <remote host IP address>
in the command prompt or terminal. The output will display the response time and the IP address of each router the ping passes through. If there is a high response time at a specific router, it could indicate an issue with that router or network segment.
Ping Flood Test: Use the ping command with the -f
flag to perform a flood test and identify the maximum packet rate before lost packets occur.
Type ping -f <remote host IP address>
in the command prompt or terminal. The output will display the packet loss rate. If there is high packet loss, it could indicate issues with the network infrastructure or the remote host.
These scenarios using ping can help troubleshoot network latency issues and identify specific points of failure in the network infrastructure. It's important to use multiple tools and tests to diagnose latency issues and ensure that your network is running smoothly.
Note that the actual round-trip time may vary depending on a variety of factors, including network congestion and the distance between the computer and the server.
Additionally, the results of the Ping command may not always be indicative of true network latency, as factors such as network congestion (WAN or LAN congestion) or device processing times can impact the accuracy of the results.
However, like mentioned before, Ping can be a useful tool for quickly getting a basic measurement of network latency.

Measuring network latency may not sound like the most exciting thing in the world, but trust us, it's crucial to keep your network running smoothly! So let's get down to it - when it comes to latency, there are different levels you need to be aware of to prioritize troubleshooting.
A "good" network latency result is typically anything under 100 milliseconds. That's less time than it takes to snap your fingers! This speed is acceptable for most applications, including web browsing, email, and file transfers.
On the other hand, a "bad" network latency result is typically anything over 100 milliseconds. As latency increases, your user experience can become increasingly frustrating - especially for applications that require real-time data transmission, like video conferencing.
But wait, there's more! A "poor" network latency result is anything over 100 milliseconds. Yikes! That's enough time to make a sandwich while you wait for your data packets to travel from one point to another. High latency can lead to significant user frustration and impaired application performance.
Of course, acceptable latency results can vary depending on the specific application or industry. For example, financial trading platforms may require extremely low latency, with acceptable or good latency rates at less than 10 milliseconds.
In general, network administrators aim to keep latency as low as possible to ensure optimal network performance and user experience. They can achieve this by optimizing network routing, increasing bandwidth, and reducing congestion on the network.
Discover the importance of network response time and how Obkio's Network Monitoring tool facilitates network response time monitoring & optimization.
Learn moreNetwork latency, or the delay in the transmission of data between two devices over a network, can be caused by a variety of factors. Here are some of the most common causes of network latency:

So there you have it, folks! Regularly Testing network latency is the key to keeping your network healthy and happy. And don't forget, it's not the only metric that matters - Packet Loss and Jitter are important too!
To calculate latency, you need to measure the round-trip time it takes for data packets to travel from one point in the network to another point and back again. Here are the steps to calculate latency:
- Choose two points in the network that you want to measure the latency between. These could be two devices, two network segments, or two different locations on the Internet.
- Send a test packet from one point to the other. The packet should contain a timestamp indicating when it was sent.
- Once the packet reaches the other point, it should be immediately sent back to the original point.
- When the original point receives the packet back, it should compare the current timestamp with the timestamp that was included in the packet. The difference between these two timestamps is the round-trip time.
- Divide the round-trip time by two to get the one-way latency.
For example, if the round-trip time is 100 milliseconds, the one-way latency would be 50 milliseconds.
To get more accurate latency measurements, you can repeat this process multiple times and take an average of the results. You can also use network performance monitoring software, like Obkio, to automate this process and get real-time latency measurements across your entire network.
Let's say you want to measure the latency between your computer and a web server. You start by sending a test packet from your computer to the web server. The packet contains a timestamp indicating the exact time it was sent.
Once the web server receives the packet, it immediately sends it back to your computer. When your computer receives the packet, it compares the current time to the timestamp that was included in the packet to calculate the round-trip time.
Let's say the round-trip time is 120 milliseconds. To get the one-way latency, you would divide this number by two, which gives you 60 milliseconds.
So in this example, the latency between your computer and the web server is 60 milliseconds. If you perform this calculation multiple times and take an average of the results, you can get a more accurate measurement of the latency. Calculating Latency in a Complex Network Architecture: Steps and Tools to Identify and Optimize Latency in Your Network
Calculating latency in a complex network architecture can be a bit more challenging than in a simple network setup. Here are a few steps you can take to calculate latency in a complex network:
- Identify the different components of your network architecture, including routers, switches, firewalls, load balancers, and servers.
- Map out the network paths between different components. This will help you identify the different segments of your network where latency might be introduced.
- Use network performance monitoring software, like Obkio, to measure latency across different segments of your network. This can help you identify which segments are causing the most latency and where you should focus your troubleshooting efforts.
- Use traceroute tools to trace the network path between two points and identify any network segments where latency might be introduced. Traceroute tools can also help you identify any bottlenecks in your network that might be causing latency.
- Monitor network traffic to identify any congestion or bandwidth issues that might be causing latency. This can help you optimize your network to reduce latency.
By following these steps, you can get a better understanding of the latency in your complex network architecture and take steps to optimize your network and improve performance.
It's worth nothing that although the round-trip time and one-way latency calculation method is the most popular and widely accessible approach for determining network performance across most enterprise use cases, other techniques exist for measuring one-way latency.
These alternatives often involve the use of specialized hardware that is synced with GPS or atomic clocks at both ends of the network connection, providing a higher degree of precision.
However, these methods are typically more complex and costly, and are primarily utilized by telecommunications companies and mobile phone networks.
Regardless of the chosen methodology, it's critical to select a technique that produces accurate results for informed decision-making on network performance while also remaining practical and cost-effective for the enterprise's requirements.
