However, to start with, testers can run speed tests on real browsers and devices using the steps outlined below. Simply sign up for free, choose the browser-device-OS combination required, and start testing site speed. Use BrowserStack’s real device cloud to check your website speed on 3000+ real browsers and devices. Analyze websites for speed levels when running browser compatibility tests. Testers must ensure that it loads across multiple browsers – older and newer versions of each. Pro-Tip: It is not enough to check if a website is loading fast on a single browser or versions of one browser.
The time is judged relative to when the page starts loading. LCP: LCP or Largest Contentful Paint is a metric that conveys the time it takes to render the largest text block or images within the viewport.DOM processing Time: Represents the time required to parse the HTML into a DOM and retrieve or execute scripts.Response Time: Represents the time taken to fully receive the first response from the server.Page load time: Represents the time taken to completely display the content of a specific page.TTFB: Time to First Byte (TTFB) represents the time taken by a web or mobile browser to receive the first byte of response from the server after it requests a specific URL.Key Metrics for Checking Website Load Time To begin with, let’s understand what these metrics represent at a high level. Additionally, calculating relevant metrics such as Time to first byte (TTFB), Response time, Page load time, DOM processing for each browser can be a cumbersome task, especially it if has to be done manually. However, testing a website’s speed across a range of real devices and browsers can be challenging without the right tools at hand.
Users access websites accessed through thousands of different devices and browsers. It also helps them evaluate which web pages are taking too long to load or identify if there is a specific browser for which the website needs to be optimized. This enables them to gain actionable insights for specific web pages. Teams must consider testing a website’s loading time across a range of device-browser combinations at regular intervals.
