Is anyone out there using 10G Ethernet or Infiniband with Cassandra in a cluster where there is a noticeable increase in performance or reduced latency to warrant the cost of the faster network connections?
Any experience or even rationale would help. We are considering Infiniband but are on the fence as to how much it would really improve performance and reduce latency (along with how stable CentOS 5.5 drivers would be). Thanks in advance for any information/feedback.
