Additional info on


The browser has sent 110 CSS, Javascripts, AJAX and image requests in order to completely render the main page of JOC. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 20 to 1 for JavaScripts and from 9 to 1 for CSS and as a result speed up the page load time.
