 * For a long time, I have always used the ‘Use Google Libraries’ plugin on WP sites
   that I run and speed tests have shown it to be effective.
 * BUT… I am just wondering if the usefulness of this has changed with HTTP/2.
 * It seems that now it is better to serve everything from a single origin server,
   rather than pulling files from different places, BUT it is still very likely 
   that users have the google libraries version of the file cached.
 * Any opinions?

 * The benefits of HTTP/2’s request multiplexing would mitigate the cost of having
   high latency to your server, true, but it doesn’t outweigh the benefits of using
   a CDN. Along with the benefits of caching, as you point out, Google’s hosted 
   libraries are hosted by Google on their probably massive world-wide network of
   servers. Their latency is almost certainly lower than yours.
 * The things that you want to get rid of with HTTP/2 are pretty simple:
 * – Domain sharding: Serving your content using multiple domains is actually worse
   now.
    – Resource concatenation: Because of multiplexing, multiple files can all
   be sent at once instead of one at a time, so concatenation of resources to a 
   single file is arguably worse overall. – Inlining of smaller resources: Server
   push mitigates the need for this by pro-actively sending resources before they’re
   explicitly requested.
 * CDNs are still good to use.
