      Map Navigation tree widget takes over 15 minutes to refresh. I currently have one main map with approximately 60 tiered sub-maps. When I try to put them in the map navigation tree widget, the widget is unable to refresh in 15 minutes causing the tree widget to be unusable.
      The submaps go 3 - 4 levels deep, with the lowest level being comprised of maps that contain about 30 hosts, each host has approximately 75 items with about 60 triggers

      Steps to reproduce:

      • Create Map including 12 submaps including 10 submaps each including 20 hosts each
      • Add this map to Dashboard Map tree widget, check the add submap checkbox

      Result:
      CPU Usage goes very high, the widget takes 3 minutes to load

      Debug info:

      Total time: 169.086932
Total SQL time: 0.518418
SQL count: 43 (selects: 30 | executes: 13)
