Thread:Project:Support desk/ResourceLoader vs CDN subdomain for css scripts/reply (7)

In addition to that it probably is faster to load your CSS and JS with the resource loader, because you should save one or two connections, the RL tries to load as much resources as possible in as least as possible connections to save the time for DNS lookup (which will normaly be cached on client side), tcp headers, webserver response and so on (in fact any overhead you need to establish a connection). Combined with the facts mentioned by TheDJ, the resource loader may not be perfect, but it makes a lot of things easier and much more performant with less work (for a developer using it) :)
