Our browser made a total of 164 requests to load all elements on the main page. We found that 90% of them (147 requests) were addressed to the original Conc.at, 5% (8 requests) were made to Fonts.gstatic.com and 2% (3 requests) were made to S.ytimg.com. The less responsive or slowest element that took the longest time to load (1.2 sec) belongs to the original domain Conc.at.
Page size can be reduced by 468.3 kB (15%)
3.1 MB
2.7 MB
In fact, the total size of Conc.at main page is 3.1 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 2.5 MB which makes up the majority of the site volume.
Potential reduce by 56.7 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. 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 56.7 kB or 76% of the original size.
Potential reduce by 68 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. Conc images are well optimized though.
Potential reduce by 137.9 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 137.9 kB or 59% of the original size.
Potential reduce by 273.6 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. Conc.at needs all CSS files to be minified and compressed as it can save up to 273.6 kB or 82% of the original size.
Number of requests can be reduced by 5 (3%)
153
148
The browser has sent 153 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Conc. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 6 to 1 for JavaScripts and as a result speed up the page load time.
