"A Cassandra compatible NoSQL column store, at 1MM transactions/sec per server."

Personal pet-peeve of mine. Using "TPS" or "Transactions/sec" to measure something that is in no way transactional. Maybe ops/sec, reads/sec, updates/sec, or something...

Add my pet peeve: not listing latency stats. Big Tables does millions of ops/sec but it can take 5(!) seconds to complete one. That's the stat that matters to customers.

The whole point of Cassandra is to run a cluster of servers to handle load at scale with minimal friction instead of having to buy a big single machine or spend all your time/money trying to run a clustered RDBMS. This test doesn't measure the correct thing.

Cassandra's performance scales linearly with the number of nodes though, so per-node performance definitely matters. Probably not 10x, but probably not 1x either.
