> cassandra-stress should output some aggregated statistics for the data that
> it outputs. In testing the performance of a Cassandra cluster it's useful to
> look at the performance by establishing what the average read/write rate is
> during the middle 80% of a stress job (the first and last 10% being outliers
> as the cluster is starting and stopping a big operation.)
> I've implemented this to add these stats to the end of the cassandra-stress
> output. It also adds a command line option to turn it off if it's not desired.
> My branch here:
