we are seeing slow down from what looks like EE trying to read/setup its session value:

this just happens to be on a single page for a ecommerce product… we use the shop plugin so it is using

i noticed in the previous report you mentioned it ran on single.php.

Is there a reason it would run on a non EE page?

In the screen shots noted, the page was:

When we deactivate the EE plugin the site slowdown stops and pages are responsive.

Not really sure what to do? Please advise.

Hi there,

The reason it runs on a non-EE page is because the ticket selector could be anywhere on the site, (like if it’s there’s a ticket selector shortcode on a page or post).

If the slowdown is related to the size of the wp-options table (because session-related transients are stored there) then it may help to install this plugin:
and delete all of the expired transients.

It may also help to update to the latest version of Event Espresso 4 because there was a session related item removed in 4.9.58.p.

so we have optimized wp-options table but not helping. we also updated to the lastest… .57 to .58. that didn’t seem to help either.

one thing we are seeing is that EE is consistently taking a bunch of time initializing it’s session on admin-ajax.php.

in that case i would assume the session is never present and one would need to be created. but also not sure why it would be running.

The current version is actually 4.9.60, and did you happen to delete those transients?

yes we have deleted the transients. also it looks like now there is a 4.9.61 available. how often are you guys updating?

It depends. Sometimes it can be a month, sometimes it can be a few days between updates.

Can you also check the server’s error logs and/or the PHP error logs? There’s also a way for WordPress to log errors by setting up WP_DEBUG_LOG. More info here:

There may be something in the error logs that will shed some light on why the session start is taking so long on your site.
