Issue Database process high CPU usage after upgrade from Onyx

Hello,

I have upgraded a virtual machine that had Plesk Onyx installed to Obsidian.

All went well as everything is functional.

For the database I have Percona 5.7. Onyx now detects that the installed database is Percona. As I said, everything is functional but the CPU usage has ramped up from around 20 ms to 200 ms (see picture attached).

Is there any explanation for this I may be missing? Web server responsiveness seems to be unaffected but I didn't test it under heavy load.

Any suggestion would be welcome :)
