Client-side programming languages ranked by average page speed

This table shows average page speeds per client-side programming language. We show two measurements, obtained from Google's Chrome User Experience Report (CrUX).

• Time to First Byte (TTFB) measures the time it takes to establish the connection to the web server until content starts to be served, see TTFB definition.
• Largest Contentful Paint (LCP) measures the time starting from when a web page first starts loading up to the point when the largest image or text block becomes visible within the page, see LCB definition.

We include client-side programming languages, for which we have at least 100 measurements, and calculate the average of these sites.

See technologies overview for further explanations on the methodologies used in the surveys.
