Subject [jira] [Created] (DISPATCH-759) Core thread consumed deleting deliveries
Date Mon, 01 May 2017 19:11:04 GMT
Chuck Rolke created DISPATCH-759:
------------------------------------

             Summary: Core thread consumed deleting deliveries
                 Key: DISPATCH-759
                 URL: https://issues.apache.org/jira/browse/DISPATCH-759
             Project: Qpid Dispatch
          Issue Type: Bug
    Affects Versions: 0.8.0
         Environment: Fedora 25 laptop
Single router, 8 worker threads, single receiver, single sender. Messages have 200 100-byte
annotations.
            Reporter: Chuck Rolke


Without the annotations the router passes 33,000 messages per second. With the annotations
the router passes about 500 messages per second. The whole router process is consumed creating
and freeing messages.

The issue exposes the fact that the router core thread is involved (90% cpu) in qdr_delete_delivery_CT.
The core thread should not be involved in deleting deliveries and freeing messages.
