             Summary: Bug fix for formula for Clock.waitUntil
                 Key: CASSANDRA-18097
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-18097
             Project: Cassandra
          Issue Type: Bug
            Reporter: Marianne Lyne Manaog


While working on benchmarking Paxos improvements in OSS Cassandra, the results for paxos variant V2 with 100 partitions is much lower than the V1. Results were shown to [~benedict] and he found the incorrect formula for waitNanos in Clock.java.

Also, tests were added to verify behaviour of ContentionStrategy backoff methods
Test behaviour fixed in CASSANDRA-18086 plus another one-line bug fix in Clock.waitUntil().
