We analyzed page load time and found that the first response time was 286 ms and then it took 2.6 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 45% of websites can load faster.

Page optimization

  • HTML 186.8 kB
    Images 1.9 MB
    Javascripts 722.5 kB
    CSS 260.5 kB

    In fact, the total size of main page is 3.1 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. Images take 1.9 MB which makes up the majority of the site volume.

    • Original 186.8 kB
    • After minification 94.0 kB
    • After compression 21.9 kB

    HTML optimization

    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 92.8 kB, which is 50% 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 165.0 kB or 88% of the original size.

    • Original 1.9 MB
    • After optimization 1.8 MB

    Image optimization

    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. DUXIANA images are well optimized though.

    • Original 722.5 kB
    • After minification 548.1 kB
    • After compression 138.4 kB

    JavaScript optimization

    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. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 584.1 kB or 81% of the original size.

    • Original 260.5 kB
    • After minification 208.8 kB
    • After compression 38.3 kB

    CSS optimization

    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. needs all CSS files to be minified and compressed as it can save up to 222.2 kB or 85% of the original size.

The browser has sent 79 CSS, Javascripts, AJAX and image requests in order to completely render the main page of DUXIANA. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 17 to 1 for JavaScripts and from 6 to 1 for CSS and as a result speed up the page load time.

As for redirects, our browser reached this domain in two steps. The first redirect led to, then it was forwarded to, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address uses IP address which is currently shared with 1 other domain. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.
