Page Optimization Overview & Recommendations

Page size can be reduced by 366.9 kB (22%)

Content Size

1.6 MB

After Optimization

1.3 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Realworld.io main page is 1.6 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. 80% 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 856.8 kB which makes up the majority of the site volume.

HTML Optimization

-85%

Potential reduce by 300.4 kB

  • Original 354.5 kB
  • After minification 345.2 kB
  • After compression 54.1 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 300.4 kB or 85% of the original size.

Image Optimization

-3%

Potential reduce by 8.5 kB

  • Original 294.3 kB
  • After minification 285.8 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. Realworld images are well optimized though.

JavaScript Optimization

-6%

Potential reduce by 52.2 kB

  • Original 856.8 kB
  • After minification 856.8 kB
  • After compression 804.7 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 5.8 kB

  • Original 138.8 kB
  • After minification 138.8 kB
  • After compression 133.0 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. Realworld.io has all CSS files already compressed.

Requests Breakdown

Number of requests can be reduced by 82 (79%)

Requests Now

104

After Optimization

22

  • Images
  • JavaScript
  • CSS

The browser has sent 104 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Realworld. 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.
