Content Size

331.7 kB

After Optimization

195.7 kB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Example.qt.io main page is 331.7 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 50% of websites need less resources to load. HTML takes 130.4 kB which makes up the majority of the site volume.

HTML Optimization

-88%

Potential reduce by 114.2 kB

  • Original 130.4 kB
  • After minification 71.3 kB
  • After compression 16.2 kB

HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. This page needs HTML code to be minified as it can gain 59.1 kB, which is 45% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 114.2 kB or 88% of the original size.

Image Optimization

-1%

Potential reduce by 315 B

  • Original 57.5 kB
  • After minification 57.2 kB

Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Example Qt images are well optimized though.

JavaScript Optimization

-0%

Potential reduce by 120 B

  • Original 57.7 kB
  • After minification 57.7 kB
  • After compression 57.6 kB

It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. This website has mostly compressed JavaScripts.

CSS Optimization

-25%

Potential reduce by 21.4 kB

  • Original 86.1 kB
  • After minification 86.1 kB
  • After compression 64.7 kB

CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Example.qt.io needs all CSS files to be minified and compressed as it can save up to 21.4 kB or 25% of the original size.

Requests Breakdown

Number of requests can be reduced by 20 (47%)

Requests Now

43

After Optimization

23

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 43 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Example Qt. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 16 to 1 for JavaScripts and from 6 to 1 for CSS and as a result speed up the page load time.
