[jira] [Created] (ZEPPELIN-3978) Scale up Jetty Server threads by using custom thread pool

zhixia dai created ZEPPELIN-3978:
------------------------------------

             Summary: Scale up Jetty Server threads by using custom thread pool 
                 Key: ZEPPELIN-3978
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3978
             Project: Zeppelin
          Issue Type: Improvement
            Reporter: zhixia dai
            Assignee: zhixia dai


By default Jetty Server only supports 200 threads.
On our daily use cases, we normally have more than 100 users on the single Zeppelin Server, which will create more than 200 threads in Jetty.

That could cause slowness or stuck because users could not receive WebSocket message.

Add configurable param feature to scale up the performance for Single Zeppelin Server whenever needs it
