> Running 2^10 rounds of bcrypt can take a while.  In environments (like PHP) where connections
are not typically long-lived, authenticating can add substantial overhead.  On IRC, one user
saw the time to connect, authenticate, and execute a query jump from 5ms to 150ms with authentication
enabled ([debug logs|http://pastebin.com/bSUufbr0]).
> CASSANDRA-7715 is a more complete fix for this, but in the meantime (and even after 7715),
this is a good option.
