We analyzed page load time and found that the first response time was 906 ms and then it took 26.7 sec to load all DOM resources and completely render a web page. This is an excellent result, as only a small number of websites can load faster. Unfortunately, there was 1 request timeout, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

Page optimization

  • HTML 30.1 kB
    Images 428.7 kB
    Javascripts 212.2 kB
    CSS 4.2 kB

    In fact, the total size of main page is 675.1 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. 65% of websites need less resources to load. Images take 428.7 kB which makes up the majority of the site volume.

    • Original 30.1 kB
    • After minification 27.8 kB
    • After compression 9.2 kB

    HTML 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. Czarnobyl Cba images are well optimized though.

    • Original 212.2 kB
    • After minification 211.8 kB
    • After compression 77.2 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 135.0 kB or 64% of the original size.

    • Original 4.2 kB
    • After minification 4.1 kB
    • After compression 1.3 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 2.9 kB or 69% of the original size.

The browser has sent 81 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Czarnobyl Cba. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 42 to 1 for JavaScripts and as a result speed up the page load time.











Possible request optimization













Normal result

IP address uses IP address which is currently shared with 4 other domains. 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.

Normal result

Visitor World Map

Country of origin for 47.8% of all visits is United States. It lies approximately 4640 miles away from the server location (Netherlands) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to United States or just closer to the user base.
