High CPU usage after migration

Hello,

I migrated a web server from Ubuntu 20.04 to Rocky Linux 9 and since then my MySQL server has activity peaks with a CPU usage close to 95% which I had not before the migration.

The last activity peak was today from 06:05AM to 06:45AM, all the time taking at least more than 90% of CPU.

It's like on this new server, the default installation comes with MySQL background activities !

What can I check when on Linux top command I see mysqld at 95% of CPU usage? Because I checked access to the web server and there isn't more users.

I really feel like there is a background process on this installation of Rocky Linux which overload MySQL.
