Our browser made a total of 167 requests to load all elements on the main page. We found that 85% of them (142 requests) were addressed to the original Cop-23.org, 5% (8 requests) were made to Fonts.gstatic.com and 2% (3 requests) were made to Fonts.googleapis.com. The less responsive or slowest element that took the longest time to load (5.8 sec) relates to the external source V1.addthisedge.com.
Page size can be reduced by 851.5 kB (9%)
9.8 MB
9.0 MB
In fact, the total size of Cop-23.org main page is 9.8 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. Images take 9.4 MB which makes up the majority of the site volume.
Potential reduce by 257.6 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 257.6 kB or 87% of the original size.
Potential reduce by 584.7 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. COP23 images are well optimized though.
Potential reduce by 4.2 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 5.0 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. Cop-23.org has all CSS files already compressed.
Number of requests can be reduced by 31 (20%)
154
123
The browser has sent 154 CSS, Javascripts, AJAX and image requests in order to completely render the main page of COP23. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 19 to 1 for JavaScripts and from 14 to 1 for CSS and as a result speed up the page load time.
