resmgr:cpu quantum

Event 'resmgr: cpu quantum' is a standard event used by resource manager to control the allocation of CPU to processes. When a session waits for 'resmgr: cpu quantum' that session is waiting to be allocated a quantum of CPU time.
This wait occurs when the resource manager is enabled and is throttling CPU consumption. To reduce the occurrence of this wait event, increase the CPU allocation for the session's current consumer group.
