    Would like to better understand "Database Caching 1/62 queries in 0.025 seconds using disk" Shouldn't there be more than 1 out of 62 query cached?

    Minified using disk
    Page Caching using disk (enhanced)
    Database Caching 1/62 queries in 0.025 seconds using disk
    Object Caching 1761/1851 objects using disk
    Content Delivery Network via.....

    A little info for dummies would be appreciated. I would like to get a basic understanding of database caching. For instance, most pages on my site, at the bottom of page source, W3TC info, have something like:

    Minified using disk
    Page Caching using disk (enhanced)
    Database Caching 13/65 queries in 0.008 seconds using disk
    Object Caching 1953/2025 objects using disk
    Content Delivery Network via...........

    However, for my home page it just reads:

    Minified using disk
    Page Caching using disk (enhanced)
    Database Caching using disk
    Object Caching 1500/1586 objects using disk
    Content Delivery Network via.........

    No queries? Help me understand?

    OK...Let me put it another way:

    What is the difference between a page source that reads:

    "Database Caching 13/65 queries in 0.008 seconds using disk"

    and one that simply reads:

    "Database Caching using disk"

    It just means at the time the cache was made it wasn't able to gather the stats to write it to the cached file.
