This post is asking the wrong question. Steve Souders (someone help me find the reference) from Google has done some measurement a few years back and concluded that you pretty much should just concat and minify every script into one file for mobile and forget about serving multiple scripts from a CDN. Setting up a connection and the latency involved on mobile is what's killing first load speed. Having that said, the problem isn't that jQuery is too big for mobile. Lots of things incur a largish download size for mobile. Bootstrap's ginormous CSS bundle first comes to mind. The biggest headache with jQuery on mobile is that it's too damn slow in execution. On a tablet where you have tons of screen space to display lots of widgets, creating largish amount (> 200) jQuery contexts can easily kill your frame rate to something < 10fps.
