You can influence it via the load-threshold and node-action-limit
cluster options.

The cluster throttles when CPU usage approaches load-threshold
(defaulting to 80%), and limits the number of simultaneous actions on a
node to node-action-limit (defaulting to twice the number of cores).

The node action limit can be overridden per node by setting the
PCMK_node_action_limit environment variable (typically in
/etc/sysconfig/pacemaker, /etc/default/pacemaker, etc. depending on
