How Caching Works?

    I've seen that XenForo uses heavy caching and that's the reason behind it's so fast.

    But, I would like to ask how XenForo invalidates a thread-listing page or post page cache so that users see latest information in ftont-end. I've seen that there's cache_lifetime => 10800 in config.php, so does this time is considered to invalidate a cache?

    XenForo doesn't use caching like that. Out of the box, it doesn't use that much (memory) caching either. If you have caching configured in config.php, that's something you added.

    Thanks Mike,

    But, what's the reason behind it's so fast?

    It's just something we try to keep in mind at all stages of development.
