FWIW, I would love to see graphs which show their compared performance
under identical write load and then show the cut-over point for reads
between the two clusters. My hypothesis is that your linux cluster
will magically be much more perfomant/less loaded due to many
linux-specific optimizations in Cassandra, but I'd dig seeing this
illustrated in an apples to apples sense with real app traffic.
