+Commentary
+==========
+
+There has been a degradation of performance observed in this release
+when compared with the previous one.
+Approximately 1% of transactions were not completed as expected for
+some use cases. Average Execution Times are extended as well.
+The unexpected results seem to point in the direction of the
+interactions of the distributed locking feature with the database.
+These areas as well as the conditions for the test need to be investigated
+further.

+ There were some failures during the 72 hour stability tests. These tests were caused by the apex-pdp pods restarting
