I was following this WordPress Optimization Guide that uses the W3 Total Cache and Smush.it to optimize my WordPress blog. After following the instructions, and bulk smushing my image library, my page went from 78/69 to 100/100. I was amazed. I went from a 3.63 second page load time to a 0.35 second page load time. I was never able to accomplish this with W3 Total Cache alone.
However, when I checked my page in other browsers and then emptied the browser cache of my current browser, my page wouldn't appear at all. I immediately went back and deactivated Smush.it. My site immediately loaded once I deactivated Smush.it.
My page is still getting a score of 100/100 with Smush.it deactivated, but it would seem I will have to activate it whenever I add an image to my image library in order to retain the benefits of the plugin. Obviously, this is not how the plugin was designed to work and will be time intensive compared to having it running in the background.
It is not a W3 Total Cache problem. It is only a problem when Smush.it is activated. Here is a link to my site:
Is there something that can be done to remedy this problem? Thanks.
