Date Tue, 19 Mar 2013 19:55:14 GMT
T Jake Luciani created CASSANDRA-5361:
-----------------------------------------

             Summary: Enable ThreadLocal allocation in the JVM
                 Key: CASSANDRA-5361
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5361
             Project: Cassandra
          Issue Type: Improvement
         Environment: JDK 6
            Reporter: T Jake Luciani
            Assignee: T Jake Luciani


Adding -XX:+UseTLAB to cassandra-env.sh yields a ~15% read performance boost.

Works with usual stress tool but also in our production.

It enables thread local allocation of new objects which makes sense for SEDA based systems.
