             Summary: Discovery: optimize resource usage for client connections
                 Key: IGNITE-3060
                 URL: https://issues.apache.org/jira/browse/IGNITE-3060
             Project: Ignite
          Issue Type: Task
          Components: general
            Reporter: Semen Boikov
            Assignee: Semen Boikov
            Priority: Critical
             Fix For: 1.6


Tried to run single server + 300 clients nodes, identified some issues which can be easily fixed:
- default size of messages history which is used to support graceful clients reconenct is too large (10 * 1024)
- now there is queue per client connection, when message is sent to clients copy is created for each queue, only one copy can be created
- each client message worker has buffered output stream, now buffer size if pretty large, actually looks like this buffered output stream is not really needed
