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. Javascripts take 816.7 kB which makes up the majority of the site volume.

    • Original 59.3 kB
    • After minification 56.9 kB
    • After compression 13.2 kB
