    @michaelandrepearce @clebertsuconic 
    You're right: these are the results of a test writing 100 Pages of 10MB with messages
of 100 bytes.
    Just 2 notes:
    - I've used the Artemis JVM default settings: -XX:+PrintClassHistogram -XX:+UseG1GC -XX:+AggressiveOpts
-XX:+UseFastAccessorMethods -Xms512M -Xmx2G.
    With smaller HEAP the effect is even more pronounced.
    - I've forced a GC just at the beginning to have the HEAP clean.
