We analyzed page load time and found that the first response time was 510 ms and then it took 1.7 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 30% of websites can load faster.

Page optimization

  • HTML 58.7 kB
    Images 143.6 kB
    Javascripts 456.4 kB
    CSS 273.4 kB

    In fact, the total size of main page is 932.1 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only 10% of websites need less resources to load. Javascripts take 456.4 kB which makes up the majority of the site volume.

    • Original 58.7 kB
    • After minification 56.2 kB
    • After compression 11.9 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 46.8 kB or 80% of the original size.

    • Original 143.6 kB
    • After optimization 135.6 kB

    Image optimization

    Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Chem Net images are well optimized though.

    • Original 456.4 kB
    • After minification 451.4 kB
    • After compression 121.6 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 334.9 kB or 73% of the original size.

    • Original 273.4 kB
    • After minification 217.7 kB
    • After compression 54.1 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 219.2 kB or 80% of the original size.

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.
