Hi Rob, thanks for your insight on the matter. We will put together a benchmark and hopefully get back with some meaningful results. We have a pair of identical servers and intend to run YCSB workloads on default datastax Cassandra community edition installations on Ubuntu & Windows. Any suggestions to make this a fair comparison (or other stress test tools?) are more than welcome.
Cheers!
