Quite true, but IMO single-node performance is largely an academic
exercise today. What production system is run without backups or
replication?

If cluster is made out of 2-3-4-10 machines, it does want to get maximum
single node performance. But I agree that in some cases we have to
sacrifice of something in order to find something new. And the larger
cluster becomes, for more things we can close eyes on.
