Thread:Project:Support desk/Using Google libraries/reply (3)

MediaWiki uses ResourceLoader which combines various libraries in grouped http requests. A CDN can be faster, but ResourceLoader is pretty efficient already. Just because it doesn't say "Google CDN" doesn't mean it's slow.

Besides, loading them from a (different) CDN won't save much as it will add an additional HTTP request just for jQuery. And it would come at the cost of having to be sure that the same version is available from the CDN, and you need to make sure to update it after each upgrade of MediaWiki.

I'd recommend you drop this and stick with ResourceLoader. Check out Manual:Cache instead.

Note that you can load libraries other than jQuery from a CDN (e.g. a plugin you use in an extension, or a special jQuery UI theme), but not libraries like jQuery itself as those are part of the default package.
