             Summary: BE: /api/v1/persist/CLUSTER_CURRENT_STATUS takes more than 2s for transferring 307KB response
                 Key: AMBARI-18407
                 URL: https://issues.apache.org/jira/browse/AMBARI-18407
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 3.0.0


Ambari UI when logging-in requests the persisted cluster status from the /api/v1/persist/CLUSTER_CURRENT_STATUS call. On a 800 node cluster this takes 2s or more to GET.
The majority of time is in the transfer of bytes. 
A 3.8s call had a wait time (time to first byte) of 815ms, and content download time of 2.98s.
We need to see if the download time can be improved.
