4.4 MB
3.8 MB
In fact, the total size of Manning.com main page is 4.4 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. 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 3.7 MB which makes up the majority of the site volume.
Potential reduce by 565.7 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 189.4 kB, which is 30% 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 565.7 kB or 89% 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. Manning images are well optimized though.
Potential reduce by 50 B
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 5 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. Manning.com has all CSS files already compressed.
Number of requests can be reduced by 26 (10%)
260
234
The browser has sent 260 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Manning. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 12 to 1 for JavaScripts and from 5 to 1 for CSS and as a result speed up the page load time.
