Page optimization

  • HTML 55.9 kB
    Images 223.3 kB
    Javascripts 0 B
    CSS 0 B

    In fact, the total size of main page is 279.2 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 25% of websites need less resources to load. Images take 223.3 kB which makes up the majority of the site volume.

    • Original 55.9 kB
    • After minification 54.9 kB
    • After compression 16.5 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 39.4 kB or 71% of the original size.

    • Original 223.3 kB
    • After optimization 221.4 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. Ob Ultrasound images are well optimized though.

Possible request optimization







Normal result

IP address uses IP address which is currently shared with 4 other domains. The more sites share the same IP address, the higher the host server’s workload is. 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.
