Some people talk big about dropping jQuery and saving one request, yet they have a shipload of bloat elsewhere. Not using jQuery in and of itself is not an optimization of any kind. I use jQuery and my page has a perfect score in GTmetrix. If the goal is optimization, you have to consider the total package.

Addititionally, jQuery loads on the first request and sits in local cache thereafter. And it could already be in local cache if you use a CDN.

It won’t be cached already. Safari, Chrome and Firefox all have partitioned cache now.
