Hi Michael, I am not comparing my results with results on that page. I mentioned only in the context of improved performance in 2.1 compared to 2.0.
That page compares performance between 2.0 and 2.1 with same hardware. I am doing the same exact thing (running 2.0.9 and 2.1.11 on same hardware, same load test, same datastax driver code etc) and expected same or better performance. BTW, I just came across an issue with datastax driver https://datastax-oss.atlassian.net/plugins/servlet/mobile#issue/JAVA-803. Not sure if we are hitting this but we are going to test with 2.1.5 driver and see if it's any better.

We are obviously not seeing that. That post compared cassandra-stress write on versions 2.0 and 2.1, each on a single AWS c3.8xlarge instance, so just be sure to compare apples to apples in observations. -- Kind regards, Michael
