Low performance of cluster management landing page



Environment has 16 nodes in the cluster.  Post upgrading to Pega 8.1.3 all the 16 nodes start and join the cluster. Long time is required for the Admin studio and the Cluster management landing page to become available though all nodes are present in the cluster. An error occurs on the User Interface (UI) and it provides an incorrect state of the environment though the page becomes available.
