High CPU usage since upgarde to 2.1

CMK version:
2.1.0p3.cre (CheckMK RAW)

OS version:
CentOS Linux release 7.9.2009


I’ve recently upgraded to version 2.1.0p3 from version 2.0.0p25.
since then I’m experiencing significantly higher CPU usage.
Is this because the new version requires more CPU resources?
Has anyone else experienced this issue?
