Subject [jira] Commented: (CASSANDRA-1968) Increase JVM young generation size
Date Tue, 11 Jan 2011 23:08:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12980412#action_12980412
] 

Peter Schuller commented on CASSANDRA-1968:
-------------------------------------------

FWIW, on JDK 1.7, using MaxGCPauseMillis set to a reasonable value may be a good idea, allowing
the VM to choose a young-gen size as large as possible to accomodate the pause time goal (while
originally introduced for G1 it's also usable with CMS, though I haven't tried how well it
works with CMS). Unfortunately this is not available before 1.7.

 We should set it explicitly.
