Large Number of Queries Created by Notification Plugin

Hello:

I set up the Notification plugin for my theme to handle submissions for a calendar on our website which needs to be moderated by one of our content administrators. I have used this plugin on other sites in the past and I am very happy with the functionality of the plugin.

One potential issue I have noticed when using the Query Monitor plugin to review the server response for our site is that the Notification plugin is creating a large number of queries on every page load (close to 200). The queries are not all the same but are similar to the following:

SELECT option_name, option_value
FROM <code>wp_smx2fcb140_options</code>
WHERE option_name IN ( '_transient_notification_comment_types', '_transient_timeout_notification_comment_types' )
UNION SELECT 'current_time', UNIX_TIMESTAMP( NOW() ) AS option_value;

The queries are being called by wp_cache_get(). These queries load on every page load on every page of our site.

I am concerned these queries may be having a negative performance impact on our site. In testing with several speed testing tools there appears to be a significant drop in performance when the plugin is activated versus when it is deactivated.

Is there anything I can do cut down or eliminate these queries? Could you also explain what the purpose of these queries are and why so many of them are run on each page load?

Please get back to me when you have a chance. Thank you for your help!
