Our browser made a total of 112 requests to load all elements on the main page. We found that 93% of them (104 requests) were addressed to the original Arduino.ua, 3% (3 requests) were made to Connect.facebook.net and 2% (2 requests) were made to Ajax.googleapis.com. The less responsive or slowest element that took the longest time to load (997 ms) belongs to the original domain Arduino.ua.

Page Optimization Overview & Recommendations

Page size can be reduced by 138.6 kB (15%)

Content Size

954.4 kB

After Optimization

815.8 kB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Arduino.ua main page is 954.4 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. 55% of websites need less resources to load. Images take 675.5 kB which makes up the majority of the site volume.

HTML Optimization

-76%

Potential reduce by 61.9 kB

  • Original 81.9 kB
  • After minification 80.1 kB
  • After compression 20.0 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 61.9 kB or 76% of the original size.

Image Optimization

-1%

Potential reduce by 8.2 kB

  • Original 675.5 kB
  • After minification 667.3 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. Arduino images are well optimized though.

JavaScript Optimization

-4%

Potential reduce by 4.7 kB

  • Original 108.8 kB
  • After minification 107.7 kB
  • After compression 104.1 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

-72%

Potential reduce by 63.9 kB

  • Original 88.2 kB
  • After minification 80.4 kB
  • After compression 24.4 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. Arduino.ua needs all CSS files to be minified and compressed as it can save up to 63.9 kB or 72% of the original size.

Requests Breakdown

Number of requests can be reduced by 9 (8%)

Requests Now

109

After Optimization

100

  • Images
  • JavaScript
  • CSS

The browser has sent 109 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Arduino. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 7 to 1 for JavaScripts and from 4 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 Arduino.ua can be misinterpreted by Google and other search engines. Our service has detected that Ukrainian is used on the page, and it matches the claimed language. Our system also found out that Arduino.ua 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.

Social Sharing Optimization
