[jira] [Created] (CASSANDRA-15125) Replace Math.random with Replace.nextDouble to remove performance overhead

bd2019us created CASSANDRA-15125:
------------------------------------

             Summary: Replace Math.random with Replace.nextDouble to remove performance overhead
                 Key: CASSANDRA-15125
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15125
             Project: Cassandra
          Issue Type: Improvement
            Reporter: bd2019us


Math.random has a slight performance overhead associated with itself that does not exist in Random.nextDouble. These instances of Math.random, such as those sampled below, can be replaced with random.nextDouble. Furthermore, the randomness can be configured via the Random class if such a feature is needed in the future.
