Click here to check amazing Linux E X P R S content for India. Otherwise, check out these important facts you probably never knew about

We analyzed page load time and found that the first response time was 1.9 sec and then it took 10.9 sec to load all DOM resources and completely render a web page. This is a poor result, as 85% of websites can load faster.

Page optimization

  • HTML 63.8 kB
    Images 572.9 kB
    Javascripts 496.4 kB
    CSS 81.9 kB

    In fact, the total size of main page is 1.2 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. 70% of websites need less resources to load. Images take 572.9 kB which makes up the majority of the site volume.

    • Original 63.8 kB
    • After minification 62.8 kB
    • After compression 14.0 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 49.7 kB or 78% of the original size.

    • Original 572.9 kB
    • After optimization 551.7 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. Linux E X P R S images are well optimized though.

    • Original 496.4 kB
    • After minification 465.5 kB
    • After compression 166.3 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 330.1 kB or 66% of the original size.

    • Original 81.9 kB
    • After minification 64.3 kB
    • After compression 15.6 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 66.3 kB or 81% of the original size.

Our browser made a total of 129 requests to load all elements on the main page. We found that 36% of them (46 requests) were addressed to the original, 8% (10 requests) were made to and 5% (7 requests) were made to The less responsive or slowest element that took the longest time to load (6.2 sec) relates to the external source

Additional info on


The browser has sent 119 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Linux E X P R S. 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 from 6 to 1 for CSS and as a result speed up the page load time.











Possible request optimization













Normal result


As for redirects, our browser was forwarded to before it reached this domain.

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


CS cs language flag


CS cs 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. Our service has detected that Czech is used on the page, and it matches the claimed language. 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 62.9% of all visits is India. It lies approximately 3960 miles away from the server location (Czech Republic) 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 India or just closer to the user base.

Poor result

Social Sharing Optimization

Open Graph description is not detected on the main page of Linux E X P R S. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
