FFPC Debug info HTML comments question

  • I’m trying to verify that caching is working on my site.

    I enable the “Add HTML debug comment” setting in the debug section of FFPC to view the HTML comment in the cached version of the pages.

    I see the HTML comment okay, which is good. Specifically, I see the first section of the HTML comment “cache generation stats”, within which, the “generation time” timestamp and date never change when I reload the page, which is good, because those timestamps are telling when the cached version was created. Correct?

    <!– WP-FFPC cache generation stats
    generation time: 0.146 seconds
    generaton UNIX timestamp: 1470600507
    generaton date: 2016-08-07T20:08:27+00:00
    generator server: XXX.XXX.XXX.XXX –>

    But in the second section, however, these timestamps do change each time I reload the page:

    <!– WP-FFPC cache output stats
    cache engine: apcu
    UNIX timestamp: 1470600900
    date: 2016-08-07T20:15:00+00:00
    from server: XXX.XXX.XXX.XXX –>

    Is this also correct?

    It is correct.

    The first entry indicated to cache entry generation stats, the second is the serving from the cache stats.

    Ok, great, thanks.

    Also, I just have a few questions regarding how FFPC uses memory:

    – Is there a way to tell how much memory FFPC is using on the server?

    – How much memory will FFPC use, on average? Does it require memory to be allocated to it in any way or will it just use free memory?

    – How can I see what is in the cache?

    Thanks again. Great plugin, btw!

    Depends on the backend you’re using. Memcached requires allocated memory, APCu doesn’t.

    – How can I see what is in the cache?
    That completely depends on the backend.

    HI all,
    I’m using your plugin on my site .. I read in my backend
    “Driver: memcached
    Stato Backend:
    127.0.0.1:20000 => up & running ”

    but if I check “Add HTML debug comment” I don’t see anything in html .. why?
    this is my site.. https://www.analisidelsangue.net – actually TTFB about 400ms

    so, how can I verify if this plugin it’s working on my site?
    thnkx for your help!

    (consider I have tried to use batcache plugin on my site without success…
    this is my configuration:
    – hosting siteground (ngix, memcached)
    – cloudflare CDN/ reverse proxy
