      Description

      On a system running 23.0.0-SNAPSHOTS in a large Cisco environment, the topology map takes several (5+) minutes to load.

      Table sizes are as follows:

      opennms=> select count(*) from node;
       count
      -------
        2028
      (1 row)
      
      opennms=> select count(*) from cdpelement;
       count
      -------
        1844
      (1 row)
      
      opennms=> select count(*) from cdplink;
       count
      -------
       35717
      (1 row)
      

      Once loaded, any action in the UI, such as panning or selecting an edge is also slow.

      We should work to identify and resolve the bottlenecks and allow the application to work smoothly on large networks.
