Sluggish load times on our calendar lately

    The past couple weeks, our WPFullCalendar page is loading very erratically…sometimes it’s fast, other times it takes 15-20 seconds to display a month. Cycling the month is equally slow. If I disable WP-FullCalendar and use the default EventsManager calendar, it loads instantly in both list/month views.

    Here’s what I’ve already tried to no avail:
    1) Disabled every plugin (except WP-FullCalendar and Events Manager) and switching to the TwentyFifteen theme.
    2) Adding Caching/Speedboost modules like Autoptimize and WP Super Cache. I wasn’t using any prior. Currently I still have Autoptimize cleaning up my CSS/JS files, but I get the same results with it turned off.
    3) Added the “Use Google Libraries” plugin as suggested by EventsManager in their settings/performance optimization page.
    4) Temporarily trashing all but ~50 events.
    5) Removing the JQuery CSS Theme from WP-FullCalendar and using “no theme”
    6) Opened a help ticket with our hosting company to see if they could flush memcache. Still waiting to hear back from them.

    The page I need help with: [log in to see the link]

    based on a quick test on webpagetest.org your main problem is the time it takes to start to receive the base HTML (also know as “time to first byte”). WP Super Cache (or a similar page cache plugin) should help greatly. other tips: make sure you’re on PHP7.x, try object caching (if available to you), improve hosting (more RAM, more CPU), …

    good luck,

    Hi Frank,

    Thanks for the reply. Currently installed PHP version is 7.0.27.

    I’ve tried various combinations of Autoptimize, WP Super Cache, and various other caching plugins…it doesn’t seem to help the WP-FullCalendar to load any faster. The rest of the site loads very quickly, it’s just the WP-FullCalendar page that is slow.

    I’m going to ask my hosting company about object caching, one of the caching plugins I tried mentioned that neither Memcache nor Redis PHP extensions are set up.

    Autoptimize (although a great plugin, obviously 😉 ) won’t help with your “time to first byte” (aka TTFB) @dexterlib. if WP Super Cache doesn’t help, try e.g. KeyCDN Cache Enabler or Hyper Cache or Comet cache instead, this is what _should_ help to get the load time down.

    Hyper Cache seems to be helping, thanks Frank!
