It's really pretty easy to saturate gigabit ethernet with a Cassandra
cluster. Mulitplying traffic by roughly RF is definitely a lose.

Having a few requests time out while the service detects badness is
typical in this kind of system. I don't think writing a completely
separate StorageProxy + supporting classes to allow avoiding this in
exchange for RF times the network bandwidth is a good idea.

We've been experiencing some cluster-wide performance issues if any single
node in the cluster is performing poorly. For example this occurs if
compaction is running on any node in the cluster, or if a new node is being
bootstrapped.
We believe the root cause of this issue is a performance optimiz
