Subject [jira] [Commented] (CASSANDRA-9558) Cassandra-stress regression in 2.2
Date Fri, 05 Jun 2015 22:03:03 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14575318#comment-14575318

Andy Tolbert commented on CASSANDRA-9558:
-----------------------------------------

Thanks [~aboudreault]!  

For reference, [JAVA-738|https://datastax-oss.atlassian.net/browse/JAVA-738] was previously
opened to evaluate the pool implementation for protocol version 3+.  I've also opened up [JAVA-802|https://datastax-oss.atlassian.net/browse/JAVA-802]
to ensure we incorporate testing java-driver RCs with cassandra-stress to ensure there is
no performance regression as part of the test/release process.   I'll continue doing a performance
evaluation of the driver with cassandra-stress to see if anything obvious sticks out on the
driver side.

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

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