1. Nodes where cardinality estimation is wrong as witnessed by collected runtime
statistics. The node with maximum discrepancy is formally a hotspot. One course of
action for performance analyst to follow is adjusting cardinality estimation (e.g. with a
hint), thus influencing the optimizer to choose a different plan.
2. Nodes where the execution have spent bulk of the time. Formally, we take cumulative
run time of a node (v$sql_plan_statistics.last_elapsed_time) and subtract cumulative run
time of it's children.
