Page optimization

  • HTML 44.3 kB
    Images 222.8 kB
    Javascripts 1.6 MB
    CSS 34.3 kB

    In fact, the total size of main page is 1.9 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. 80% 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. Javascripts take 1.6 MB which makes up the majority of the site volume.

    • Original 44.3 kB
    • After minification 44.0 kB
    • After compression 12.7 kB

    HTML optimization

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.

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 1.1 MB or 66% of the original size.

    • Original 34.3 kB
    • After minification 29.7 kB
    • After compression 6.8 kB

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.
