Page optimization

  • HTML 115.8 kB
    Images 3.4 MB
    Javascripts 245.0 kB
    CSS 298.9 kB

    In fact, the total size of main page is 4.1 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. 75% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Images take 3.4 MB which makes up the majority of the site volume.

    • Original 115.8 kB
    • After minification 106.0 kB
    • After compression 15.4 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.
