1.9 MB
In fact, the total size of Dockercon.com main page is 2.9 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. Images take 2.1 MB which makes up the majority of the site volume.
Potential reduce by 19.5 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. 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 19.5 kB or 72% of the original size.
Potential reduce by 522.8 kB
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, Docker Con needs image optimization as it can save up to 522.8 kB or 25% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.
Potential reduce by 290.9 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. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 290.9 kB or 54% of the original size.
Potential reduce by 164.8 kB
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. Dockercon.com needs all CSS files to be minified and compressed as it can save up to 164.8 kB or 82% of the original size.
Number of requests can be reduced by 25 (42%)

The browser has sent 59 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Docker Con. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 10 to 1 for JavaScripts and from 4 to 1 for CSS and as a result speed up the page load time.
