High CPU usage, dashboard slows down, lost connection with cache plugins

    Hi,
    Ever since WP was updated to v5.5 we have been facing high CPU usage problems. We have the latest NewsPaper theme and Wp-Rocket installed as cache plugin and Yoast as SEO plugin. Suddenly from the last 2-3 days we have been facing high CPU usage problem.

    We have 2 dedicated CPU cores and 4GB RAM on the server but still, the CPU usage is going to 80-100% all the time. We did R&D and removed WP-Rocket and put in WP fastest Cache and still, the CPU usage is between 75-95%. Because of which the site slows down a lot and backend is slow too.

    With all the plugins deactivated, the dashboard is still really slow and CPU usage is between 10-25%, which is very strange. Any help will be appreciated.

    Hello @m3gadeath,

    Some WordPress users are experiencing issues with their plugin, theme or slow loading times due to WordPress 5.5 update. One of the reason of this issue is that some plugin or theme are still using old code.

    In the case of my client installing jQuery Migrate Helper and updating the theme fix the issue temporarily.

    Please check it out and let us know if it resolves the issue for you.

    Best,

    Hi,
    We did install Jquesrry migrate helper.
    It shows us the following:

    This page generated the following warnings:

    
https://www.gadgetbridge.com/wp-content/themes/Newspaper/includes/wp-booster/wp-admin/js/tagdiv-theme-plugins-setup.js: jQuery.fn.load() is deprecated
https://www.gadgetbridge.com/wp-content/plugins/td-composer/assets/js/js_files_for_wp_admin.min.js: jQuery.fn.load() is deprecated
Please make sure you are using the latest version of all of your plugins, and your theme. If you are, you may want to ask the developers of the code mentioned in the warnings for an update.

    Dashboard has become really slow for logged in users, also the front end of the site has slowed down too, is there a way we can go back to the previous WordPress release till these issues are sorted?

    You might still need to update your plugin and theme.

    Hi,
    I did update the theme and the plugins.
    But I still having high CPU issues. Very strange and this happens as soon as an editor/author/admin logs into the WordPress Admin panel/dashboard.

    Hi, we found the culprit, the cache plugin was creating a conflict when we put redis object cacheing plugin on. We saw some problems and deactivated and deleted the redis plugin, but that plugin did not delete all its cache files.
    Finally, in error log it showed that redis conflicting file and we deleted that. Now the dashboard/admin panel is much better.

    Also, then Yoast with newspaper theme also slows the dashboard down. But the main culprit was that Redis object cache plugin, which does not work with WP-rocket nor with Wp-Fastest cache.

    Thanks
