Page Optimization Overview & Recommendations

Page size can be reduced by 253.1 kB (7%)

Content Size

3.4 MB

After Optimization

3.1 MB

  • HTML
  • Images
  • JavaScript

In fact, the total size of Lttf.ieee.org main page is 3.4 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. Only a small number of websites need less resources to load. Images take 3.0 MB which makes up the majority of the site volume.

HTML Optimization

-90%

Potential reduce by 189.6 kB

  • Original 210.6 kB
  • After minification 114.4 kB
  • After compression 20.9 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 96.1 kB, which is 46% 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 189.6 kB or 90% of the original size.

Image Optimization

-2%

Potential reduce by 61.8 kB

  • Original 3.0 MB
  • After minification 3.0 MB

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. Lttf IEEE images are well optimized though.

JavaScript Optimization

-1%

Potential reduce by 1.7 kB

  • Original 142.4 kB
  • After minification 142.3 kB
  • After compression 140.7 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.

Requests Breakdown

Number of requests can be reduced by 59 (60%)

Requests Now

99

After Optimization

40

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 99 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Lttf IEEE. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 43 to 1 for JavaScripts and from 11 to 1 for CSS and as a result speed up the page load time.
