Click here to check amazing Engineering Docker content for China. Otherwise, check out these important facts you probably never knew about engineering.docker.com
Docker is a platform designed to help developers build, share, and run modern applications. We handle the tedious setup, so you can focus on the code.
Visit engineering.docker.comWe analyzed Engineering.docker.com page load time and found that the first response time was 9 ms and then it took 2.4 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 45% of websites can load faster.

Our browser made a total of 123 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original Engineering.docker.com, 63% (78 requests) were made to Docker.com and 7% (9 requests) were made to Cdn.cookielaw.org. The less responsive or slowest element that took the longest time to load (566 ms) relates to the external source Docker.com.
Page size can be reduced by 251.8 kB (14%)
1.8 MB
1.6 MB
In fact, the total size of Engineering.docker.com 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. 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. Javascripts take 691.5 kB which makes up the majority of the site volume.
Potential reduce by 215.9 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 215.9 kB or 82% of the original size.
Potential reduce by 0 B
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. Engineering Docker images are well optimized though.
Potential reduce by 12.9 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. This website has mostly compressed JavaScripts.
Potential reduce by 23.0 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. Engineering.docker.com has all CSS files already compressed.
Number of requests can be reduced by 67 (61%)
110
43
The browser has sent 110 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Engineering Docker. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 27 to 1 for JavaScripts and from 24 to 1 for CSS and as a result speed up the page load time.
