EPL taking too much database resources, bring site down!

The only slow page is loading the Dashboard > Plugins as the license checker looks for the latest version of the plugin. The profiler bundles all the statistics into a single metric which includes the loading of the Dashboard > Plugins page which has nil effect on the front end and overall site performance.

We use the popular plugin called Easy Digital Downloads which manages licensing.

If you perform a manual test and browse the site the results are very different when excluding the Dashboard > Plugins page.

We have this plugin powering thousands of listings on a single site with near instant response times.

RE W3 Total Cache. I’ve never had success in configuring this plugin and use WP-Cache as its much easier to configure and provides excellent speed improvements.

We also write the plugin with WP_debug = true and generate no errors on any parts of the plugin. Some themes or custom code may be producing errors so be sure to check your error_log in the root of your WordPress folder. Or enable debugging and check your site for errors which cause slowdowns.

If your site is live and you want to display the debug errors just for you, what you can do is:

First, you’ll need to know your outgoing IP address. Google My IP to get your IP address.

Then edit your wp-config.php (CAREFUL) by replacing:

define(‘WP_DEBUG’, false);

with

if ($_SERVER[‘REMOTE_ADDR’] == ‘123.123.123.123’) {
define(‘WP_DEBUG’, true);
} else {
define(‘WP_DEBUG’, false);
}
