We analyzed page load time and found that the first response time was 1.4 sec and then it took 26.4 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 134.7 kB
    Images 1.0 MB
    Javascripts 387.3 kB
    CSS 131.6 kB

    In fact, the total size of main page is 1.7 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. 55% of websites need less resources to load. Images take 1.0 MB which makes up the majority of the site volume.

    • Original 134.7 kB
    • After minification 121.2 kB
    • After compression 25.8 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. 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 108.9 kB or 81% of the original size.

    • Original 1.0 MB
    • After optimization 946.1 kB

    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. Czero images are well optimized though.

    • Original 387.3 kB
    • After minification 377.7 kB
    • After compression 131.0 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 256.3 kB or 66% of the original size.

    • Original 131.6 kB
    • After minification 125.3 kB
    • After compression 24.0 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 107.6 kB or 82% of the original size.

Our browser made a total of 149 requests to load all elements on the main page. We found that 2% of them (3 requests) were addressed to the original, 24% (36 requests) were made to and 5% (7 requests) were made to The less responsive or slowest element that took the longest time to load (20.4 sec) relates to the external source

Additional info on


The browser has sent 145 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Czero. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 34 to 1 for JavaScripts and from 14 to 1 for CSS 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.

Language and encoding

Good result


N/A  language flag


N/A  language flag





Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else) and no language is claimed in <html> or <meta> tags either. Our system also found out that 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.

HTTPS certificate

SSL Certificate has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.

Normal result

Visitor World Map

Country of origin for 100% of all visits is South Korea. It’s good for that their server is also located in South Korea, as that enables the majority of their visitors to benefit from a much faster page load time.
