Page optimization

  • HTML 209.7 kB
    Images 611.4 kB
    Javascripts 688.2 kB
    CSS 489.2 kB

    In fact, the total size of main page is 2.0 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. 55% of websites need less resources to load. Javascripts take 688.2 kB which makes up the majority of the site volume.

    • Original 209.7 kB
    • After minification 202.4 kB
    • After compression 28.3 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 181.4 kB or 87% of the original size.

    • Original 611.4 kB

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

    • Original 688.2 kB
    • After minification 571.7 kB
    • After compression 189.2 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 499.0 kB or 73% of the original size.

    • Original 489.2 kB
    • After minification 472.2 kB
    • After compression 104.8 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. needs all CSS files to be minified and compressed as it can save up to 384.5 kB or 79% of the original size.

Our browser made a total of 39 requests to load all elements on the main page. We found that 69% of them (27 requests) were addressed to the original, 13% (5 requests) were made to and 13% (5 requests) were made to The less responsive or slowest element that took the longest time to load (463 ms) relates to the external source
