Our browser made a total of 47 requests to load all elements on the main page. We found that 0% of them (0 request) were addressed to the original Websocket-spec.java.net, 2% (1 request) were made to Github.com and 2% (1 request) were made to Avatars.githubusercontent.com. The less responsive or slowest element that took the longest time to load (3.5 sec) relates to the external source Github.com.

Page Optimization Overview & Recommendations

Page size can be reduced by 151.3 kB (51%)

Content Size

298.4 kB

After Optimization

147.1 kB

  • HTML
  • Images
  • CSS

In fact, the total size of Websocket-spec.java.net main page is 298.4 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. 70% of websites need less resources to load. HTML takes 176.6 kB which makes up the majority of the site volume.

HTML Optimization

-83%

Potential reduce by 146.0 kB

  • Original 176.6 kB
  • After minification 168.0 kB
  • After compression 30.6 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 146.0 kB or 83% of the original size.

Image Optimization

-22%

Potential reduce by 287 B

  • Original 1.3 kB
  • After minification 1.0 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, Websocket Spec Java needs image optimization as it can save up to 287 B or 22% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

CSS Optimization

-4%

Potential reduce by 5.0 kB

  • Original 120.4 kB
  • After minification 116.1 kB
  • After compression 115.4 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. Websocket-spec.java.net has all CSS files already compressed.

Requests Breakdown

Number of requests can be reduced by 43 (93%)

Requests Now

46

After Optimization

3

  • Images
  • JavaScript
  • CSS

The browser has sent 46 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Websocket Spec 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 39 to 1 for JavaScripts and from 6 to 1 for CSS and as a result speed up the page load time.

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Websocket-spec.java.net can be misinterpreted by Google and other search engines. Our service has detected that English is used on the page, and it matches the claimed language. Our system also found out that Websocket-spec.java.net main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.
