Hello @desmetjozef
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
It is working fin eon our end:

The Query Monitor would show an error for a slow query in their toolbar if there was an issue.
Assuming you are using the latest version of all the plugins, themes, and WordPress (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.

Please do something with this.
Why this marked as solved when it’s not?
I switched back to version 1.0.51 and it was all good. The website speed was as it should be. But, today I’ve updated again to 1.0.52.3 with the hope that the problem is fixed and nothing. The website is slow like hell.
Here is the real problem:

Also, why do you run this call on both front and back-end when, ideally, should be called on in WP admin?
I have the PRO version also and created a ticked here: https://support.rankmath.com/ticket/big-performance-issue/
