I very rarely see heterogeneous vnode counts in the same cluster. I would almost guarantee you are the only one doing this with MVs as well. That said, since you have different IO hardware, are you sure the system configurations (eg. block size, read ahead, etc) are the same on both machines? Is dstat showing a similar order of magnitude of network traffic in vs. IO for what you would expect? -- ----------------- Nate McCall Wellington, NZ @zznate CTO Apache Cassandra Consulting http://www.thelastpickle.com
