[w3-total-cache] Doesn't seem to be caching.

  • When I run my site students.scisdragons.net through some caching testers like:

    https://www.webpagetest.org/
    And
    https://loadimpact.com/

    And it doesn’t seem to be caching. It’s a dedicated server running several virtualhosts on Ubunut.

    My Compatability test is below. What can I do to get things working better/faster.

    It does. Please see the source of the site. Here is the part that you might want to have a look…

    You may want to put JS at the bottom (if possible) or load them asynchronously. You may want to use a CDN for images. You may also want to go with a good DNS manager as the DNS look up took about 0.5 seconds that is considered very high, IMO.

    Do not use disk for database caching, use APC. You might also want to try changing your page caching to disk enhanced and see if you get some improvements.
