I can't find any reference to w3 total cache in the source code so I would like to understand if it's working.
I was using Wp Super cache+CloudFlare and my website was loading in approx 3 secs (in first view) according to http://www.webpagetest.org.
I installed W3tc yesterday (WP Super Cache has been removed, CloudFlare is still working) and set it up but loading times through the same server raised up to approx 5 secs.
If I disable the plugin, the time raises up to approx 6 secs, so I suppose it's working, but there are no references in the source code.
Could you please help me to understand why the code is not appearing and how to check? Thanks
