[jira] [Created] (CASSANDRA-9558) Cassandra-stress regression in 2.2

Alan Boudreault created CASSANDRA-9558:
------------------------------------------

             Summary: Cassandra-stress regression in 2.2
                 Key: CASSANDRA-9558
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9558
             Project: Cassandra
          Issue Type: Bug
            Reporter: Alan Boudreault
            Priority: Blocker


We are seeing some regression in performance when using cassandra-stress 2.2. You can see the difference at this url:

http://riptano.github.io/cassandra_performance/graph_v5/graph.html?stats=stress_regression.json&metric=op_rate&operation=1_write&smoothing=1&show_aggregates=true&xmin=0&xmax=108.57&ymin=0&ymax=168147.1

The cassandra version of the cluster doesn't seem to have any impact.
