Hi
Even when using W3 Total Cache my site is still pretty slow despite a fast server response time, I ran it through pagespeed.googlelabs.com and I see 2 ways I think you could improve performance by default.
Google says:
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Remove render-blocking JavaScript:
…-includes/js/jquery/jquery.js?ver=1.11.2
…s/jquery/jquery-migrate.min.js?ver=1.2.1
Also why not let Google host & deliver common libraries like jQuery to minimise requests to my own server?

Do you have any recommended settings for W3 Total Cache?
