Are you sure the client isn't the bottleneck? Have you tried running the client on independent (and perhaps multiple) machines? What does "nodetool tpstats" say while you run the test? (Try running it several times in a row and observe how it changes.) > Regarding the ring balancing - I assume it should be balanced.

A 'nodetool compact' on all nodes (when not actively writing) followed by 'nodetool ring' should confirm that you're balanced across the nodes. -- / Peter Schuller
