Page optimization

  • HTML 25.0 kB
    Images 5.7 kB
    Javascripts 28.5 kB
    CSS 6.2 kB

    In fact, the total size of Dlib.net main page is 65.5 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. Javascripts take 28.5 kB which makes up the majority of the site volume.

    • Original 25.0 kB
    • After minification 23.7 kB
    • After compression 6.8 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 18.2 kB or 73% of the original size.

    • Original 5.7 kB
    • After optimization 5.5 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. Dlib images are well optimized though.

    • Original 28.5 kB
    • After minification 27.4 kB
    • After compression 11.2 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 17.3 kB or 61% of the original size.

    • Original 6.2 kB
    • After minification 4.2 kB
    • After compression 1.2 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. Dlib.net needs all CSS files to be minified and compressed as it can save up to 5.0 kB or 80% of the original size.

Visitor World Map

Country of origin for 36.2% of all visits is India. It lies approximately 8690 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 Dlib.net page load time for the majority of users is moving the server to India or just closer to the user base.

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:
