-------------------------------------------

             Summary: Consider reverting to CMS GC on 3.0
                 Key: CASSANDRA-10403
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10403
             Project: Cassandra
          Issue Type: Improvement
          Components: Config
            Reporter: Joshua McKenzie
             Fix For: 3.0.0 rc2


Reference discussion on CASSANDRA-7486.

For smaller heap sizes G1 appears to have some throughput/latency issues when compared to
CMS. With our default max heap size at 8G on 3.0, there's a strong argument to be made for
having CMS as the default for the 3.0 release.
