Firstly, you’ll need to log out to see the HTML comments regarding performance. I viewed one of the pages on your site and got the following when I viewed the page source ( just above </head>
):
First View ( uncached ):
<!-- Page generated without caching in 1.29125404358 seconds. -->
Second View ( cached ):
<!-- Served by Codespanker Cache in 0.174492120743 seconds. -->
Given those numbers, your site served the content over 86% faster with the cache than without it.
Try viewing the page again while you’re logged out and let me know what you find.
Secondly, when you ran those tests, was the cache already set from you viewing the homepage? If so, both the first and second views may not be that much different.
Note: Keep in mind that the time it takes for your site to serve the content ( which is reported by the caching plugin ) is not the same as the time it takes for your site to actually load in a browser.
