> Possible improvements for {{SCMNodeManager#getNodeStatistics}}:
> - avoid repeated {{getAllNodes()}} calls, store and reuse the list
> - avoid repeated iteration of nodes for {{nodeStateStatistics}} (by each {{get...NodeCount()}} method)
> - {{nodeUsageStatistics}} may base its calculations on values aggregated by {{nodeSpaceStatistics}} instead of iterating storage reports itself
