Over the past couple of weeks, the server response time on the main Events page for my site has increased terribly. It’s taking upwards of 30 seconds to load everything.
The page in question is https://www.rockymountainsewing.com/sewing-classes/. Though all 700+ queries (for around 50 events per month) are executing in less than 1 second, the server response time is always over 6 seconds.
We have the month view as the default.
As a test on my staging site, I disabled all the Events Calendar plugins: TEC, TEC Pro, Event Tickets, Event Tickets Plus, TEC Filter Bar and TEC shortcodes. Once the cache was flushed and rebuilt, the server response time went down to an acceptable level of less than 0.2 seconds.
For the 2nd test, I did the opposite. I enabled all the plugins mentioned, disabled all other plugins, and enabled the 2014 theme. Within a couple of tests, the server response time went back up to over 6 seconds.
I love your plugins, but this is a major struggle. Our search traffic is falling fast, so we need some help making it right.
Thanks,
CraigSorry…I was able to resolve this. The issue occurred as a result of trying to get the month view indexed by removing the noindex meta tag. That causes the following to occur according to Brook at this link: https://wordpress.org/support/topic/events-calendar-causes-high-mysqlcpu-load
“The problem in that topic comes our Month View Cache not yet having a throttle. When you enable month view caching in WP-Admin > Events > Settings > Display it will cache the months that you view, lessening the number of queries done for a given month view by many fold. But, when someone unleashes a spider on your website this can cause the site to cache many thousands of month view pages, eventually making the database cache gigantic.”
I disabled that function, cleared the cache, and the issue is starting to resolve itself.
