Answer from AI
The website loading speed can be measured using various metrics and tools:
- Time to First Byte (TTFB) — the time from the request to receiving the first byte of response from the server.
- Full Page Load Time — when all resources (images, scripts, styles) are loaded.
- First Contentful Paint (FCP) — the time when the browser first rendered any content.
- Largest Contentful Paint (LCP) — the time it takes to load the largest visible element.
- Total Blocking Time (TBT) — the time during which the user cannot interact with the site.
Tools for measurement include:
- Google Lighthouse — a built-in Chrome tool for performance auditing.
- WebPageTest — an online service with detailed metrics.
- Chrome DevTools — the Performance tab for load analysis.
Example of using Lighthouse in Chrome:
- Open the website in Chrome.
- Press F12, go to the "Lighthouse" tab.
- Run the audit and get a report with loading speed metrics.
