Page optimization

  • HTML 316.8 kB
    Images 243.1 kB
    Javascripts 48.0 kB
    CSS 1.2 MB

    In fact, the total size of main page is 1.8 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. 75% 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. CSS take 1.2 MB which makes up the majority of the site volume.

    • Original 316.8 kB
    • After minification 265.9 kB
    • After compression 27.0 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 51.0 kB, which is 16% 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 289.8 kB or 91% of the original size.

    • Original 243.1 kB
    • After optimization 239.3 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. 3M Select images are well optimized though.

    • Original 48.0 kB
    • After minification 46.4 kB
    • After compression 17.0 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 31.0 kB or 65% of the original size.

    • Original 1.2 MB
    • After minification 1.1 MB
    • After compression 188.6 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 972.7 kB or 84% of the original size.

Our browser made a total of 32 requests to load all elements on the main page. We found that 3% of them (1 request) were addressed to the original, 88% (28 requests) were made to and 3% (1 request) were made to The less responsive or slowest element that took the longest time to load (4.3 sec) relates to the external source

Additional info on


The browser has sent 29 CSS, Javascripts, AJAX and image requests in order to completely render the main page of 3M Select. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 5 to 1 for JavaScripts and from 9 to 1 for CSS and as a result speed up the page load time.











Possible request optimization













Normal result


As for redirects, our browser reached this domain in two steps. The first redirect led to, then it was forwarded to, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

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.
