WP Super Cache Vs. W3 Total Cache

There are a lot of articles and comments floating around the Internet on what the best WordPress plugin is to speed up page load times. I've done some testing with WP Super Cache and W3 Total Cache to come up with my own conclusion and I think the findings are pretty interesting.Test Setup:
  • New Media Temple GS server setup for the test
  • Fresh WordPress Install
  • Sample post created with minimal text and 2 images
  • Page load speed tested 3 times, alternating between two domains, using webpagetest.org
Initial Results:Admittedly, WP Super Cache managed to eke out a victory on a base WordPress Install. It sped up WordPress by about .3 seconds and all seemed well with the world.WP Super Cache Vs. W3 Total CacheIf this had been the end of the story, you could stop reading here, but the simple truth is that we all like to use lots of plugins with WordPress and that is where I really began seeing the value of W3 Total Cache. There are lots of settings that can be tweaked and you can even add a CDN, so I was able to get things moving much more quickly in the long run with W3 Total Cache.After installing around 14 highly used plugins, what I noticed is that, while the first page loading time was a little longer, subsequent page loads were quite a bit faster, in general, with W3. I was also able to squeeze out a little better of a compressed image score, after installing WP Smush.it with W3. No real noticeable change was noticed with WPSC.WP Super Cache Vs. W3 Total CacheWhile the tests are not highly scientific, based on the ability to customize many more settings and overall faster page loading speeds, W3 will be my go-to for speeding up WordPress sites.List of Installed Plugins Tested:
