Network Latency – Common Causes and Best Solutions

What are the causes of network latency? Here are the common culprits: Distance, faulty network components, viruses, and computer worms. Keep reading to learn more about network latency. Hopefully, this article will help you find a solution to your network problems. There are many factors to consider when calculating latency, so avoid them.

WAN latency

WAN latency can be a severe problem for any business, but it is particularly troublesome in large networks. This is because the speed of light, while seemingly infinite, is definitely a sign of high latency, and the routers delay packets. Although this can result in significant latency, the delay is on the order of tens of microseconds. This difference can have a dramatic impact on a business’s ROI.

WAN latency is one of the most common factors that influence internet latency. Any time a network is busy directing traffic, it causes a delay. That delay affects resources on the local network, the internet, and other networks. A company can use a software application to improve the latency of its network. This application can then improve its responsiveness. But, first, monitoring network performance and optimizing the application for all network conditions is essential.


There are a few reasons for this relationship. Distance, for one, is the time it takes to travel a specified distance. Network latency, on the other hand, is the time it takes to transfer data over a network. The latency caused by distance can vary greatly, and there are multiple ways to measure it. This paper explores how distance and network latency can be combined to reduce network latency. To understand how they affect each other, consider how you would measure the distance between two places.

In modern networks, distance is a significant source of latency. It is also known as propagation delay. For example, if you are connecting two places, the distance between those locations is 20,000 kilometers. For every 100 kilometers, you will need approximately five milliseconds of latency. If the distance is much shorter, such as in a city, multiply the distance by two. The second most significant factor, serialization delay, used to compete with distance but is not as critical now.

Computer worms

When a worm infects your computer, the scan rate increases, a worm called the Sapphire Worm was estimated to double its size and 90 percent of all vulnerable hosts within 10 minutes. This is not only a large number, but it also creates latency. As a result, you might see slowdowns in your network.

The first thing to do when a worm infects your computer is to quarantine it and then remove it from your computer. The quarantined process will be stripped of all worm code execution permissions, and if you notice suspicious behavior, you can kill it. Keep your system updated with the latest security updates to minimize the risk. Keeping up with security patches and malware removal tools is essential. If you do not update your antivirus and security software regularly, you risk falling victim to malicious worms.


You are not alone if you have experienced latency problems in your network. Many people ask about the typical values of network latency. The answer varies depending on the network you’re using and the distance between the server and your location. Latency calculators are an excellent tool for checking the impact of latency on network performance. You can even use them to identify the causes of latency and how to resolve them.

Using a network monitoring tool, you can determine which devices are consuming the most data. Often, the devices on a network aren’t operating at a high enough speed to keep the network running efficiently. You can increase the network’s throughput by monitoring endpoint usage and reducing these devices’ data consumption. But remember that more latency means lower throughput and worse performance for end-users.

Internet connection type

Network latency is the time it takes for data to travel across a network. DSL, cable, and satellite Internet all have different latency levels. Latency is also affected by other factors, such as the type of Internet connection. The higher the number of hops in your relationship, the greater the latency. To minimize latency, keep your bandwidth usage low and focus on large images and other files.

In simple terms, latency and bandwidth are different. Although they measure the amount of time it takes to transfer data, they have different meanings. Bandwidth measures how much data you can download at a time. Download speed differs from latency, but they affect the quality of your online experience. While both are important, higher bandwidth will give you better performance. Hence, you should always check your bandwidth before purchasing a new internet connection.
