> Key: DISPATCH-1379
> URL: https://issues.apache.org/jira/browse/DISPATCH-1379
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Affects Versions: 1.8.0
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
> Priority: Major
>
> Code inspection reveals three function calls per message that may be
> eliminated and a buffer free that could be executed outside of holding the
> content lock.
> * Message allocator initializes object in memory ascending order
> Despite the size of the code, setting the required fields to zero directly is
> faster that calling ZERO.
> * Eliminate redundant calls to pn_link_get_context
> * Free empty pending buffer outside of content lock
