I've installed and activated the plug-in, but I'm not sure it's having any effect.
I ran a speed test via gtmetrix.com with the plug-in actived and deactivated--and the results are the same.
(I'm running W-3 Total Cache, for what it's worth, but I turned minify and the CDN off while running the tests--and refreshed the cache before each test.)
Am I missing something? Should there be an increase in the page loading speed?
