Our browser made a total of 111 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original Dnsjava.org, 76% (84 requests) were made to Github.githubassets.com and 19% (21 requests) were made to Avatars.githubusercontent.com. The less responsive or slowest element that took the longest time to load (305 ms) relates to the external source Github.com.

Page Optimization Overview & Recommendations

Page size can be reduced by 418.3 kB (29%)

Content Size

1.5 MB

After Optimization

1.0 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Dnsjava.org main page is 1.5 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 844.3 kB which makes up the majority of the site volume.

HTML Optimization

-85%

Potential reduce by 364.2 kB

  • Original 430.5 kB
  • After minification 421.2 kB
  • After compression 66.2 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. 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 364.2 kB or 85% of the original size.

Image Optimization

-18%

Potential reduce by 7.7 kB

  • Original 43.1 kB
  • After minification 35.5 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, DNS Java needs image optimization as it can save up to 7.7 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 40.7 kB

  • Original 844.3 kB
  • After minification 844.3 kB
  • After compression 803.6 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

-4%

Potential reduce by 5.7 kB

  • Original 138.6 kB
  • After minification 138.6 kB
  • After compression 132.9 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. Dnsjava.org has all CSS files already compressed.

Requests Breakdown

Number of requests can be reduced by 82 (75%)

Requests Now

109

After Optimization

27

  • Images
  • JavaScript
  • CSS

The browser has sent 109 CSS, Javascripts, AJAX and image requests in order to completely render the main page of DNS Java. 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 10 to 1 for CSS and as a result speed up the page load time.
