Welcome to homepage info - get ready to check Linux best content for China right away, or after learning these important things about

We analyzed page load time and found that the first response time was 1.6 sec and then it took 18.8 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.

Page optimization

  • HTML 91.4 kB
    Images 773.0 kB
    Javascripts 113.4 kB
    CSS 108.1 kB

    In fact, the total size of main page is 1.1 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. 35% of websites need less resources to load. Images take 773.0 kB which makes up the majority of the site volume.

    • Original 91.4 kB
    • After minification 89.1 kB
    • After compression 18.8 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 72.5 kB or 79% of the original size.

    • Original 773.0 kB
    • After optimization 715.9 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 images are well optimized though.

    • Original 113.4 kB
    • After minification 95.4 kB
    • After compression 32.2 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 81.2 kB or 72% of the original size.

    • Original 108.1 kB
    • After minification 99.8 kB
    • After compression 21.7 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 86.4 kB or 80% of the original size.

Our browser made a total of 71 requests to load all elements on the main page. We found that 3% of them (2 requests) were addressed to the original, 94% (67 requests) were made to and 3% (2 requests) were made to The less responsive or slowest element that took the longest time to load (10.1 sec) relates to the external source

Additional info on


The browser has sent 70 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Linux. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 9 to 1 for JavaScripts and as a result speed up the page load time.

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 Chinese is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. 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.

Poor result

Visitor World Map

Country of origin for 93.6% of all visits is China. It lies approximately 7200 miles away from the server location (United States) 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 China or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of Linux. 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:
