Major performance degradation after update from 4.6.7 to 4.8.2
-
After upgrading a client’s WordPress version from 3.8 to 4.5.3 and updating the Email Users plugin from 4.6.7 to the latest 4.8.2, we experienced a major degradation in performance when loading the admin page. I installed P3 to understand what was causing the performance degradation and it indicated that Email Users was adding over 3 seconds to each page load. After disabling the plugin in our QA site, the page load dropped from 3.8 seconds to 0.6 seconds.
Here is the breakdown timing graph with the Email Users plugin enabled:

Here are the list of plugins I currently have installed on the server:
- Contact Form 7
- Fusion Core
- Quick Page/Post Redirect Plugin
- Revolution Slider
- Share Per View
- WooCommerce
- WooCommerce – Autocomplete Orders
- WooCommerce Checkout Manager
- WooCommerce Export Customer Email
- WP Video Lightbox
- Yoast SEO
Please let me know if you need any additional information that I can provide.
