Page load time is a measure of how long it takes for a web page to fully load in a user’s browser. It is an important metric to consider when evaluating the performance of a website, as it can have a significant impact on the user experience and the overall success of a website.
There are several statistics that are commonly used to measure page load time, including:
Time to First Byte (TTFB): This measures the time it takes for the first byte of data to be received by the user’s browser after a request is made. It is a measure of the responsiveness of the server and the network.
DomContentLoaded (DCL): This measures the time it takes for the initial HTML of the page to be parsed and the DOM to be constructed. This is an indication of the time it takes for the page to be usable.
Fully Loaded Time: This measures the time it takes for all resources (e.g. images, scripts, stylesheets) on the page to be fully loaded. This is an indication of the time it takes for the page to be fully functional.
Speed Index: This is a measure of the visual progress of a page load. It takes into account how quickly the contents of a page are visibly populated.
Start Render: This measures the time it takes for any visible content to be rendered on the screen.
It’s worth noting that page load time can be affected by various factors, including the user’s internet connection, the size and number of resources on the page, the complexity of the code, and the hosting environment. To have a complete picture of the website’s performance, it is recommended to measure and analyze multiple metrics and statistics, and not rely on just one.
