We analyzed page load time and found that the first response time was 357 ms and then it took 6.6 sec to load all DOM resources and completely render a web page. This is a poor result, as 80% of websites can load faster.

Page optimization

  • HTML 126.5 kB
    Images 1.0 MB
    Javascripts 2.1 MB
    CSS 243.6 kB

    In fact, the total size of main page is 3.4 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. Javascripts take 2.1 MB which makes up the majority of the site volume.

    • Original 126.5 kB
    • After minification 119.9 kB
    • After compression 34.2 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 92.2 kB or 73% of the original size.

    • Original 1.0 MB
    • After optimization 958.2 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. The Switch images are well optimized though.

    • Original 2.1 MB
    • After minification 2.1 MB
    • After compression 602.7 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 1.5 MB or 71% of the original size.

    • Original 243.6 kB
    • After minification 242.7 kB
    • After compression 49.8 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 193.9 kB or 80% of the original size.

Our browser made a total of 148 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original, 26% (38 requests) were made to and 20% (29 requests) were made to The less responsive or slowest element that took the longest time to load (1.7 sec) relates to the external source

Additional info on


The browser has sent 136 CSS, Javascripts, AJAX and image requests in order to completely render the main page of The Switch. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 52 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 was forwarded to before it reached this domain.

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.
