This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 70% of websites need less resources to load. Images take 716.0 kB which makes up the majority of the site volume.

    • Original 112.6 kB
    • After minification 107.9 kB
    • After compression 22.4 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 90.2 kB or 80% of the original size.

    • Original 716.0 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. NCBI Insights Nlm Nih images are well optimized though.

    • Original 69.8 kB
    • After minification 69.8 kB
    • After compression 24.9 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 44.9 kB or 64% of the original size.

    • Original 26.7 kB
    • After minification 23.2 kB
    • After compression 4.1 kB

    CSS optimization
