High CPU usage after updating Yoast

Hello Onlanka,

I am sorry to learn about the high CPU usage that you noticed. To identify the source of the issue and troubleshoot, we would like to request you to check the following steps:
1. Are all your non-Yoast plugins and themes up to date?
2. If you temporarily disable the Yoast SEO plugin, do you still notice stress in the 3. server?
4. Can you confirm your server has all the proper requirements? If you are not sure, speak to your host provider. This guide explains more: https://yoast.com/help/plugin-requirements/
5. If you go to SEO > Tools, have you completed the SEO data optimization process? This will often significantly improve site performance.
6. Does the issue still happen if you go to SEO > General > Features and disable the Text Link Counter, Insights, and Link Suggestions? See the image for what needs to be disabled: https://ibb.co/k9G6N3m.
7. Can you send us additional information about any PHP errors related to Yoast SEO in your email or the server error logs? You can find the errors yourself by enabling WP_DEBUG in your wp-config.php file, trying to activate Yoast SEO, and then sending us any Yoast SEO errors in the debug.log file. You can find more details in this article: How to Use WP_DEBUG. You can also check with your web host to see if there’s a related error in your PHP error logs.

Sorry finally found the cause of the problem.

In the same day your final update released, my hosting provider overloaded the server with more clients.

So this is not related to Yoast, sorry for the misunderstand.
