Internet latency is the secret enemy of internet (broadband) users and slows down the superfast internet connections. If you are a broadband user and looking at the listed download speed that service providers are proudly advertising is actually half and other half id latency. In this article, you will learn about connection speed and how it is measured, what is internet latency and its main causes with useful ways to reduce it.
It is the speed of data transferring between your devices and the internet – it is also known as bandwidth.
There are two types of Internet connection speed:
The connection speed depends on a number of factors such as the type of connection either fiber or copper cables, line quality and the distance from the cabinet.
The internet speed is measured in megabits per second (Mbps) and shortened to Mb like 10Mb or 20Mb. Moreover, a bit is the smallest unit of data and you can also see kilobits per second (Kbps) or Kb.
1 Kbps = 1,000 Bits per second
1 Mbps = 1,000,000 Bits per second
The higher the number of megabits per second (Mbps) you have, the faster internet speed should be:
If your connection download speed is 80Mbps and an upload speed of 20Mbps. Using this speed, you can download 500Mb of photos or media within 10 seconds. and upload the 70Mb file on the internet within 3 seconds. If the host server is based on a dedicated server having great bandwidth then it will also help to reduce the latency time.
In simple words, Latency = Delay. It is the amount of delay time it takes to send any information from one point to another. If you consider the internet latency then it is the user action and response from the requested website or round trip time from the web browser to the server.
The ideal internet latency level is 0 but the effects of distance and delays caused by internet infrastructure equipment. It means latency can never be removed completely instead of minimizing. Latency has directly affect SEO and decreases the website performance, so there are maximum chances for a user to leave the website or application.
If you are a windows user then open the command prompt by searching “cmd” in your start bar. A black screen will be opened then write “ping” and type the IP address or URL of any website on the internet and press enter. Your computer measures the minimum, maximum, and average time it takes to send and receive a piece of data to that particular web address in milliseconds (ms). I am checking the Google.co.uk latency time as you can see in the picture
If you are looking at the answer for what is a good latency speed for internet then average speed faster than 50ms is considered as ideal speed for most purposes and slower than 100ms will cause problems. What is a good latency number or what is acceptable latency for internet? Remember, between 50 and 100ms is the good internet latency rate that is perfect. It is also important to look at the minimum and maximum speeds as well. If you experience a big difference between the minimum and maximum speed then your connection is unstable and data can be lost completely as you try to send or receive it. In order to confirm the stability of the internet connection, you need to run the test several times.
This process was windows users, so if you are using any other operating system then there are many websites are available to measure your internet latency rate: You can visit Pingtest or meter for this purpose.
Following are the major causes that have direct impact on your internet latency:
If you implement these techniques listed below then internet latency can be reduced. When you will reduce the server latency it will help you to load web resources faster.
Use HTTP/2 to minimize internet speed latency. It will help you to reduce server latency by minimizing the number of round trips from the sender to the receiver using parallelized transfers.
Using a CDN the resources will be closer to the end-user by caching them in multiple locations based on their geographical locations all over the world. Once all resources are cached then the user requests only needs to communicate with the nearest point of presence to retrieve requested data instead of accessing the origin server each time.
Pre-fetching web resources don’t necessarily reduce the internet latency rate but it improves the website’s perceived performance. If you have implemented pre-fetching then intensive latency processes take place in the background when users browse any particular page. So, when they click on a subsequent page, and the DNS lookups have already taken so it will loads the page faster.
It is another useful technique to reduce the internet latency because browsers cache particular resources of any website locally in order to improve latency rate and also decrease the users’ requests back to the server.
Latency is an unavoidable part of networking ecosystems, so we can minimize it instead of completely eliminating it. However, the techniques mentioned in this article are important in order to reduce the website’s latency and help you to improve page load speed for end-users.
