Inefficient application interaction with data/the database and inefficient SQL
can be particularly problematic.

Depends if your application workload can be logically partitioned such that
your db services can direct independent workloads to different nodes -
otherwise if you treat rac like a black box then there is often a tendency for
cluster waits to have a high impact as you round robin requests for the same
data to different nodes.
