A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottleneck near that server. Content types include web objects, downloadable objects (media files, software, documents), applications, real time media streams, and other components of internet delivery (DNS, routes, and database queries).

New in Tiki5 in the Performance admin panel, you can pick a Content Delivery Network for static images and jQuery code.
JQuery CDN and Vue.js on Tiki22
Vue.js will not load when "Use CDN for JavaScript" is set to jquery or Google. You have to keep the default (use none). This may be true also for prior and newer versions.
Without any server configuration, you can from the admin panel, pick Google as the CDN for your jQuery files.
