Our browser made a total of 119 requests to load all elements on the main page. We found that 0% of them (0 request) were addressed to the original Devhub.ca, 2% (2 requests) were made to Bat.bing.com and 2% (2 requests) were made to Tags.srv.stackadapt.com. The less responsive or slowest element that took the longest time to load (527 ms) relates to the external source Lighthouselabs.ca.
Page size can be reduced by 1.8 MB (21%)
8.7 MB
6.9 MB
In fact, the total size of Devhub.ca main page is 8.7 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. 85% 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. Images take 8.1 MB which makes up the majority of the site volume.
Potential reduce by 149.3 kB
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 26.7 kB, which is 14% 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 149.3 kB or 79% of the original size.
Potential reduce by 1.7 MB
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. Obviously, Devhub needs image optimization as it can save up to 1.7 MB or 21% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.
Potential reduce by 2.5 kB
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. This website has mostly compressed JavaScripts.
Potential reduce by 0 B
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. Devhub.ca has all CSS files already compressed.
Number of requests can be reduced by 20 (18%)
111
91
The browser has sent 111 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Devhub. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 21 to 1 for JavaScripts and as a result speed up the page load time.
