W3 Total Cache
What do I need to use object cache? (5 posts)

    So I've installed W3 and now I want to use object caching with it.

    What do I have to do?

    Do I have to follow all the instructions under Software Installation for Dedicated or do I have to choose only one solutions there?

    I'm a bit confused about what those are.

    Do you have object caching modules installed on your server (memcached or APC)?

    I did not know I had to install just one of then. I've installed all :(

    I guess that's why my CPU usage is high now.

    What should I do?

    If you have APC installed (which seems the case), then you should just be able to activate object cache by ticking the 'enable object cache' box in the w3tc settings, and select APC as your engine.
