Myroslav Papirkovskyi created AMBARI-18698:
----------------------------------------------

             Summary: Filter by roles in Users List page takes upto 20 secs to load with 1000+
users
                 Key: AMBARI-18698
                 URL: https://issues.apache.org/jira/browse/AMBARI-18698
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.4.0
            Reporter: Myroslav Papirkovskyi
            Assignee: Myroslav Papirkovskyi
            Priority: Blocker
             Fix For: 2.4.2


Two performance issues seen on cluster with 2000 users:

# Observed that filters by Role like "Ambari Administrator, Cluster User" on Users List pgae
- takes between 15-20 seconds to load the page
# Additionally once a filter is applied, when we apply a second filter to change the number
of users displayed on the page from default value of 10 to say 25, that also takes about 15
secs to load
