Subject [jira] [Commented] (CASSANDRA-10403) Consider reverting to CMS GC on 3.0
Date Wed, 30 Sep 2015 15:55:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14937041#comment-14937041

Jonathan Shook commented on CASSANDRA-10403:
--------------------------------------------

To be clear, in some cases, we found G1 to be a better production GC, and those tests simply
allowed us to verify this before leaving it in place.

> 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.
