Page optimization

  • HTML 303.6 kB
    Images 200.0 kB
    Javascripts 1.4 MB
    CSS 250.3 kB

    In fact, the total size of Jacionline.org main page is 2.1 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. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 1.4 MB which makes up the majority of the site volume.

    • Original 303.6 kB
    • After minification 242.9 kB
    • After compression 56.6 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 60.7 kB, which is 20% 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 247.0 kB or 81% of the original size.

    • Original 200.0 kB
    • After optimization 196.2 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. Jacionline images are well optimized though.

    • Original 1.4 MB
    • After minification 1.4 MB
    • After compression 475.5 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 913.6 kB or 66% of the original size.

    • Original 250.3 kB
    • After minification 250.2 kB
    • After compression 42.4 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. Jacionline.org needs all CSS files to be minified and compressed as it can save up to 207.8 kB or 83% of the original size.

Redirects

As for redirects, our browser reached this domain in 6 steps. The first redirect led to https://secure.jbs.elsevierhealth.com/action/getSharedSiteSession?redirect=http%..., then it was forwarded to https://secure.jbs.elsevierhealth.com/action/getSharedSiteSession?rc=1&redirect=..., and afterwards it was sent to http://jacionline.org/action/consumeSharedSessionAction?SERVER=WZ6myaEXBLGvmNGtL... and a few other URLs (see the full list below) before we finally managed to reach this website. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address

Jacionline.org 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.
