Other thoughts: - is internode_compression set to 'all' in cassandra.yaml (should be 'all' by default, but worth checking since you are using lz4 on the client)? - are you using server-to-server encryption ? You can compare the output of nodetool netstats on the test cluster with the AWS cluster as well to see if anything sticks out. -- ----------------- Nate McCall Austin, TX @zznate Co-Founder & Sr. Technical Consultant Apache Cassandra Consulting http://www.thelastpickle.com
