[ClusterLabs] What is the mechanism for pacemaker to recovery resources

I have a three node cluster of about 50 resources. When I reboot three nodes at the same time, I observe the resource by "crm status". I found that pacemaker starts 3-5 resources at a time, from top to bottom, rather than start all at the same time. Is there any parameter control?
It seems to be acceptable. But if there is a resource that can not start up because of a exception, the latter resources recovery will become very slow.I don't know the principle of pacemaker recovery resources.In particular, order and priority.Is there any suggestions?Thank you very much!
