Subject [jira] Commented: (CASSANDRA-1968) Increase JVM young generation size
Date Tue, 11 Jan 2011 23:52:45 GMT


Peter Schuller commented on CASSANDRA-1968:

Attaching a version that does that calculation. Not yet intended for direct inclusions; some
of the numbers are arbitrary and maybe it should be cleaned up a bit.

Also, correcting myself on JDK 1.7: With CMS it's apparantly MaxGCMinorPauseMillis for young-gen
(MaxGCPauseMillis). Very brief testing did not work well but probably because I failed to
tweak some other setting to allow it to dynamically size properly. Nevermind, since 1.7 isn't
out yet.

 We should set it explicitly.
