As we all know that on internet speed plays a vital role.
We might wait for a video to load fully but our tolerance to a loading website is less than three seconds. At this moment “time to first byte” (TTFB) comes into action.
Trying to connect to a web server is a multi-phase process where each phase may result in delays. If a website is sluggish or irresponsive, the secret to enhancing user experience is being able to determine the cause of the slowdown.
TTFB assists enterprises in finding weak points in the linking process. By knowing where delays occur, enterprises may change their services to work more efficiently and more consistently. Since the speed of a website will affect its web search rankings, TTFB has become essential to maximizing performance and growing visibility.
Time to first byte (TTFB) is a metric for evaluating web server response. It calculates the amount of time between establishing a server connection and loading a web page’s contents.
What components affect TTFB?
Three components have an impact on the TTFB metric:
- The time it requires for your request to move to the webserver across the network.
- The time period it takes the webserver to analyze the request and to produce the result.
- The duration takes for the answer to transmit back to your browser through the network.

- In the “Browser” dropdown menu, select the web browser that you’re using.
- In the end, press the “Start Test” button.

Ways to Improve Your Time to First Byte
You have to do something to speed up your website. Here are some points to improve TTFB.

The most common page speed metric, calculated by developers and advertisers, is “Time to First Byte” While significant, this is just a small piece of the loading profile of the modern web page.
You should strive for 500ms or less Time to First Byte over a high-speed link and 1 second or less over 3G. This provides you a better chance to encourage consumers to make page interactive in the 3 seconds before bouncing from your website.
