Page size can be reduced by 384.5 kB (28%)

Content Size

1.4 MB

After Optimization

1.0 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Cups4j.org main page is 1.4 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 75% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 853.7 kB which makes up the majority of the site volume.

HTML Optimization

-85%

Potential reduce by 284.4 kB

  • Original 336.1 kB
  • After minification 326.6 kB
  • After compression 51.7 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. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 284.4 kB or 85% of the original size.

Image Optimization

-18%

Potential reduce by 2.8 kB

  • Original 15.3 kB
  • After minification 12.5 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. Obviously, Cups4j needs image optimization as it can save up to 2.8 kB or 18% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

JavaScript Optimization

-5%

Potential reduce by 42.6 kB

  • Original 853.7 kB
  • After minification 853.7 kB
  • After compression 811.1 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

-29%

Potential reduce by 54.8 kB

  • Original 188.6 kB
  • After minification 182.4 kB
  • After compression 133.8 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. Cups4j.org needs all CSS files to be minified and compressed as it can save up to 54.8 kB or 29% of the original size.

Requests Breakdown

Number of requests can be reduced by 83 (89%)

Requests Now

93

After Optimization

10

  • Images
  • JavaScript
  • CSS

The browser has sent 93 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Cups4j. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 74 to 1 for JavaScripts and from 11 to 1 for CSS and as a result speed up the page load time.
