There are several aspects to consider when performing a website speed test. Also, keep in mind that not every speed testing tool will give you the same results, so it's important to understand what to look for when performing the test.
Caching
Test sites that have and don't have file caching enabled to see if caching helps or hurts you.
Localization
You may get different website speed test results in car owner data different locations. Often, loading times are faster in a location closer to the server location.
Try different tests
You will soon find out for yourself that each speed test can yield different results, so we recommend using multiple tools and running several tests.
Tracked metrics
It is important to understand what you are watching.
Page load time: The time it takes for a page to fully load.
Time to First Byte (TTFB): How long it takes for the browser to receive an HTML request from the server. A low score may indicate a large number of large files or server changeover time.
Number of HTTP requests: A new request is sent each time the page loads.
Core Web Vitals
Largest Content Color: The time it takes to load the largest image or text element on the page. This is the actual visual rendering time of the page.
First Entry Delay: How long it takes for a user to interact with the page (click a button/link or scroll the page).
