We analyzed page load time and found that the first response time was 1.3 sec and then it took 11 sec to load all DOM resources and completely render a web page. This is a poor result, as 90% of websites can load faster.

Page optimization

  • HTML 226.8 kB
    Images 210.9 kB
    Javascripts 256.1 kB
    CSS 23.2 kB

    In fact, the total size of main page is 717.0 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. 15% of websites need less resources to load. Javascripts take 256.1 kB which makes up the majority of the site volume.

    • Original 226.8 kB
    • After minification 194.6 kB
    • After compression 24.6 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 32.2 kB, which is 14% 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 202.2 kB or 89% of the original size.

    • Original 210.9 kB
    • After optimization 204.6 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. Systematic images are well optimized though.

    • Original 256.1 kB
    • After minification 217.8 kB
    • After compression 61.3 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 194.8 kB or 76% of the original size.

    • Original 23.2 kB
    • After minification 12.4 kB
    • After compression 2.8 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 20.4 kB or 88% of the original size.

Our browser made a total of 89 requests to load all elements on the main page. We found that 96% of them (85 requests) were addressed to the original, 2% (2 requests) were made to and 1% (1 request) were made to The less responsive or slowest element that took the longest time to load (5 sec) belongs to the original domain

Additional info on


The browser has sent 88 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Systematic. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 10 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 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.

Language and encoding

Normal 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 big5. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

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 Hong Kong. It’s good for that their server is also located in Hong Kong, as that enables the majority of their visitors to benefit from a much faster page load time.
