Subject [jira] [Commented] (CASSANDRA-10403) Consider reverting to CMS GC on 3.0
Date Wed, 14 Oct 2015 17:57:06 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957385#comment-14957385
] 

Joshua McKenzie commented on CASSANDRA-10403:
---------------------------------------------

{code:title=debian/init}
+CASSANDRA_CONF=$CONFDIR
{code}
I'm wary of this change - are there ramifications outside just the scope of the jvm.options
file to us changing debian/init in this way?

[~mshuler]: Are you the one that's most knowledgeable about the debian init/install scripts?
If so, what are your thoughts?

> 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.
