[Plugin: W3 Total Cache] Nothing is being cached

    Hey boy’n’girls,

    To push the performance of my shared-hosted blog https://www.urbanartcore.eu, I decided to use W3 Total Cache (Version 0.9.2.4) due to its great reputation. Unfortunately nothing happens after installing – and when I say nothing, I mean nothing is being cached, there’s no W3 Total Cache related html-comment in the footer of my pages, and I don’t know what to do yet…

    Here’s what I’ve done:

    • Followed the installation-guide, provided on the plugin site here on wordpress, (everything went fine)
    • Set up my setting, using ‘Opcode: eAccelerator’ (as it is provided by my hoster)
    • Deployed everything without trouble
    • Checked my sites in a different browser, cleared browser cache, checked again,…
    • Result: Nothing happens and the site is still slow.
    • Checked the .htaccess files as described in the plugin’s install section – everything’s fine.
    • Tried Debugging – but also no changes to the html-sites.
    • Googled a lot – couldn’t find help…

    Here are my ‘compatibility check’ results:

    alright then,

    I played around some more with the settings and came up with the following solution:

    • Page chace enabled – Disk enhanced
    • Minify enable – Disk
    • Database cache enabled – eAccelerator
    • Object cache enabled – eAccelerator
    • Browser cache enabled
    • CDN disabled

    Furthermore I had to uncheck CSS minify and gzip compression for JS and CSS due to encoding problems (the resulting js/css file were encoded wrong…). Now the caching system is running anyway!

    By the way, if you know any good (Cloud)-Hoster with excellent W3 Total Cache support, let me know – probably I going to move my pages to another one…

    Concerning Cloud hosting, I’d suggest Rackspace. They have cloud hosting as well as CDN. It integrates seamlessly with W3tc.

    After running a page speed test on your site, I am getting 8.2 seconds to load. Not horrible, but but with a TTFB of 0450ms, you can get a lot better times on your site.. Google gives you a page speed score of 79. Live-able.

    To speed it up, definitely get a CDN setup. As you are not minifying your JS or using Cookies, I would suggest both of those…

    69% of your requests are for images, so really work on compressing those. A CDN will work for that. Another way to reduce your photo load time is to host them on another account (i.e. Flickr) and hot link them to your site.
