[jira] [Created] (DISPATCH-70) Configurable initial-credit and credit batching needed for incoming links

Ted Ross created DISPATCH-70:
--------------------------------

             Summary: Configurable initial-credit and credit batching needed for incoming links
                 Key: DISPATCH-70
                 URL: https://issues.apache.org/jira/browse/DISPATCH-70
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Container
            Reporter: Ted Ross
            Assignee: Ted Ross
             Fix For: 0.3


Dispatch is currently hard-wired to issue initial credit for 1000 messages and to replenish credit by one for every received message.

Recent research done by Mick Goulish suggests that better performance can be achieved by batching credit replenishment by 10-50 credits at a time, thus amortizing the cost of flow processing.

Initial credit and batch size should be configurable in the router.  It might make sense to have a global configuration and per-connection configuration.
