在客户端下载时，Kendo js需要花费太多时间

I am using kendo ui scheduler in my project but while downloading the kendo js and css on client side takes too much time due to which some slowness is seen our website. To overcome this issue, we are trying to download the kendo js and css as per request means on only that page where scheduler calender is loaded. While integration the same we are unable to add the dependency "kendo.directive". Please suggest how to add that dependency or an alternative way to reduce that much delay.
