Page optimization

  • HTML 15.6 kB
    Images 273.3 kB
    Javascripts 1.5 kB
    CSS 147.5 kB

    In fact, the total size of Debian.org main page is 437.9 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only 5% of websites need less resources to load. Images take 273.3 kB which makes up the majority of the site volume.

    • Original 15.6 kB
    • After minification 14.9 kB
    • After compression 4.6 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. 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 11.0 kB or 71% of the original size.

    • Original 273.3 kB
    • After optimization 268.7 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. Debian images are well optimized though.

    • Original 1.5 kB
    • After minification 1.2 kB
    • After compression 607 B

    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 919 B or 60% of the original size.

    • Original 147.5 kB
    • After minification 139.4 kB
    • After compression 26.9 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. Debian.org needs all CSS files to be minified and compressed as it can save up to 120.6 kB or 82% of the original size.

IP address

Debian.org 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.

Claimed

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Debian.org 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), while the claimed language is English. Our system also found out that Debian.org 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

Debian.org 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 18.4% of all visits is United States. It’s good for Debian.org that their server is also located in United States, as that enables the majority of their visitors to benefit from a much faster page load time.

Social Sharing Optimization

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