Can you elaborate on to what exactly you were testing on the Cassandra
side?  It sounds like what this post refers to as "node" encryption
corresponds to enabling "internode_encryption: all", but I couldn't
guess what your client encryption is since Cassandra doesn't support
that out of the box yet.  (Which is highly relevant since that's where
most of the slowdown you observed comes from.)
