The performance was better after disabling the asoCleanup feature for Init and Update requests (charging-settings)  from asoCleanupOperationList="TERMINATE,CANCEL,INITIATE,UPDATE to asoCleanupOperationList="TERMINATE,CANCEL", and rolling upgrade (RU) of all ECE cluster members. However, the asoCleanup feature is required and needs to be enabled.
