ChugR opened a new pull request #518: DISPATCH-1354: Annotation processing performance improvements
URL: https://github.com/apache/qpid-dispatch/pull/518
 
 
   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
