I have noticed a performance degradation from 4.0.7 to 5.0.1, and 5.0.1 to 5.1.1. Both
in creating new StatelessSessions, and executing them.
I am attaching a portable test case which shows the degradation. Please refer to the
test.zip!/README.txt file for full instructions and explanation.
For the purpose of this jira description (and to show the degradation from a high-level),
here is sample output. Note that the run*.sh scripts only create new StatelessSessions,
but do not execute them. The exec*.sh scripts also execute the StatelessSessions.
