Our browser made a total of 75 requests to load all elements on the main page. We found that 32% of them (24 requests) were addressed to the original Wolframfoundation.org, 41% (31 requests) were made to Wolframcloud.com and 23% (17 requests) were made to Wolframcdn.com. The less responsive or slowest element that took the longest time to load (1.8 sec) relates to the external source Wolframcloud.com.

Page Optimization Overview & Recommendations

Page size can be reduced by 315.2 kB (18%)

Content Size

1.8 MB

After Optimization

1.4 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Wolframfoundation.org main page is 1.8 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 970.7 kB which makes up the majority of the site volume.

HTML Optimization

-74%

Potential reduce by 9.2 kB

  • Original 12.5 kB
  • After minification 10.7 kB
  • After compression 3.2 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 1.8 kB, which is 14% 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 9.2 kB or 74% of the original size.

Image Optimization

-0%

Potential reduce by 0 B

  • Original 517.6 kB
  • After minification 517.6 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. Wolfram Foundation images are well optimized though.

JavaScript Optimization

-16%

Potential reduce by 159.4 kB

  • Original 970.7 kB
  • After minification 968.5 kB
  • After compression 811.3 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. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 159.4 kB or 16% of the original size.

CSS Optimization

-58%

Potential reduce by 146.6 kB

  • Original 254.5 kB
  • After minification 251.0 kB
  • After compression 107.9 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. Wolframfoundation.org needs all CSS files to be minified and compressed as it can save up to 146.6 kB or 58% of the original size.

Requests Breakdown

After Optimization

18

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 58 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Wolfram Foundation. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 31 to 1 for JavaScripts and from 11 to 1 for CSS and as a result speed up the page load time.
