      Work Description: michaelandrepearce commented on issue #2427: 
ARTEMIS-2170 Optimized CoreMessage's checkProperties and 
cleanupInternalProperties methods
URL: https://github.com/apache/activemq-artemis/pull/2427#issuecomment-456115918
 
 
   > @michaelandrepearce I have checked that is not less optimized because the 
original version was failing to find the prefixed properties to remove ie was 
looping every property with a slower method
   
   Reply, is there a test proving that? Im very suprised, as i can see that the 
internal flag when debugging master is being set correctly if i set one of 
those two headers.

> CoreMessage::checkProperties perform too many volatile read/write and has a 
> too big body just to handle exceptional cases, while 
> cleanupInternalProperties is called on the hot path of session send, but is 
> performing too many synchronized operations and loopup on TypedProperties.
