Interaction between page cache and object cache

    Hi Stanley, can you please explain about the interaction between page cache and object cache, if both are activated?

    I have memcache installed for object cache for my dynamic content pages in buddyPress, and normal disk cache for other pages.

    Will LiteSpeed automatically detect dynamic content and use object cache, and disk cache for other pages?

    Should I exclude BP members/ members/* in the exclude settings, when I have object cache activated?

    How can I see if BuddyPress content are actually being cached with memcache?

    Regards
    Carsten

  • In general speaking, page cache is a cache for output HTML, object cache is a cache for WordPress get_option() from a database.

    So when a user loads a fresh page, the response usually likes HTML <=== PHP <=== Database. Page cache can make HTML response directly from the server, object cache can get the option from memory instead of Database.

    If you are turned ON object cache all the non-cached page will look for object cache when get option is running.

    For BuddyPress, I remember you’ve installed the patched version before, normally you don’t need to put extra URI on “exclude setting”. May I know which issue you are facing now?

    Hi Stanley, you are right, I have the patched version installed, but it is hard to see any difference in performance in BuddyPress pages.

    In what way does this patched version stand out from the standard version, and are all settings tuned for BuddyPress, or should I make any changes in the Optimization Settings from the standard settings? I have turned on object cache and memcache.

    The main issue I’m facing is speed performance. But I’m using fifty plugins, so it may be as good as it gets.

    When I activate ‘Fast Velocity Minify’ I get a speed boost, but my host provider said that my pages were not cached with this plugin active, are there any conflicts with using this with LiteSpeed?

    The patched version is added ESI for user menu and auto-purge when user page update. So it’s not directly affecting the speed.

    We have similar features as Fast Velocity Minify on Setting > Optimization page which can help you to boost up your site, have you tried those setting? Also, which speed performance are you concern? You can provide?your Report Number (found in?WP Admin > LiteSpeed Cache > Report) for us to check is there any suggestion we can provide.

    Hi,

    I’m going to mark this topic “Resolved,” due to lack of activity.

    If you still need help, please provide the previously requested information.

    We’ll be happy to reopen the topic if necessary.

    Thanks!

    P.S. You can use Fast Velocity Minify with LiteSpeed Cache at the same time, as long as you don’t try to duplicate functions. This post explains in more detail.
