Description

In findRuleNodeStatusReports, we have massive slowness in the creation of resulting NodeStatusReports, even if everything is correctly fetched from cache
Indeed, it recreates for each nodes NodeStatusReport and AggregatedStatusReports, and it easily take 9s for 1000 nodes, as the creation of these object involves a lot lot of merge, group, filter, etc
