Page optimization

  • HTML 22.4 kB
    Images 809.9 kB
    Javascripts 578.5 kB
    CSS 125.1 kB

    In fact, the total size of main page is 1.5 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. 35% of websites need less resources to load. Images take 809.9 kB which makes up the majority of the site volume.

    • Original 22.4 kB
    • After minification 19.9 kB
    • After compression 5.7 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. This page needs HTML code to be minified as it can gain 2.4 kB, which is 11% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 16.7 kB or 74% of the original size.

    • Original 809.9 kB
    • After optimization 360.1 kB

The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

    • Original 578.5 kB
    • After minification 483.3 kB
    • After compression 148.0 kB

    JavaScript optimization

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 430.5 kB or 74% of the original size.

    • Original 125.1 kB
    • After minification 110.7 kB
    • After compression 16.0 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.
