jQuery serving from Google (or other CDN) rather than local server
Google Page Analytics tools tell me that my website (www.sammamishmosque.com) has 3 blocking JS scripts, 2 of which are jQuery (jQuery.js and jQuery-migrate.js). But my question is my website serving its own instance of jQuery in the first place? Why does my instance of WordPress not use Google's CDN version of JS (the article talking about why is here)? Or the JS CDN? That way my users don't have to download them from my site and, since their browser already has a copy of the latest jQuery, my page download is much smaller. Moreso the non-existant download is not blocking my page rendering.
