Description

-Xmx1G and -Xms1G is more production ready as folks tend to leave the defaults in place.
-Dorg.apache.activemq.UseDedicatedTaskRunner=true made sense for small numbers of connections and for earlier versions of the broker that used fewer thread pools.

With the current impl, sharing threads makes more sense by default, so -Dorg.apache.activemq.UseDedicatedTaskRunner=false (the default) is preferable.
