[jira] [Created] (CASSANDRA-6746) Reads have a slow ramp up in speed

Ryan McGuire created CASSANDRA-6746:
---------------------------------------

             Summary: Reads have a slow ramp up in speed
                 Key: CASSANDRA-6746
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6746
             Project: Cassandra
          Issue Type: Bug
            Reporter: Ryan McGuire
         Attachments: 2.1_vs_2.0_read.png

On a physical four node cluister I am doing a big write and then a big read. The read takes a long time to ramp up to respectable speeds.
