             Summary: Interrouter annotation processing uses slow methods
                 Key: DISPATCH-1354
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1354
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Router Node
    Affects Versions: 1.7.0
            Reporter: Chuck Rolke
            Assignee: Chuck Rolke


Message annotation processing on received messages stages key names byte by byte into a flat buffer and then uses strcmp to check them.

Easy improvements are:
 * Use name in raw buffer if it does not cross a buffer boundary
 * If name crosses a boundary then use memmoves to get the name in chunks
 * Check the name prefix only once and then check variable parts of name strings
 * Don't create unnecessary qd_iterators and qd_parsed_fields
 * Don't check names whose lengths differ from the given keys
