Major performance regression with 10.6.11

    Details

      Description

      After upgrading part of our systems to 10.6.11 the MariaDB server uses much more CPU compared to 10.6.10.

      We were upgrading to 10.6.11 for the fix to MDEV-29843, but started to roll back due to load issues with that version.

      Server config is the same as on MDEV-29843;
      ~8 MariaDB instances per server, issue is worse on systems with a higher number of queries, where it's using 100% cpu, with notocable repsonsiveness of the system
