Robert Stupp commented on CASSANDRA-7486: ----------------------------------------- Nice :) Looking forward to see Oracle JVM and C* 2.1 results. (TBH, I don't expect much difference between OpenJDK8 and Oracle JDK8) But more interesting would be how G1 behaves w/ read and mixed workloads. > Compare CMS and G1 pause times > ------------------------------ > > Key: CASSANDRA-7486 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7486 > Project: Cassandra > Issue Type: Test > Components: Config > Reporter: Jonathan Ellis > Assignee: Shawn Kumar > Fix For: 2.1.4 > > > See > http://www.slideshare.net/MonicaBeckwith/garbage-first-garbage-collector-g1-7486gc-migration-to-expectations-and-advanced-tuning > and https://twitter.com/rbranson/status/482113561431265281 > May want to default 2.1 to G1. > 2.1 is a different animal from 2.0 after moving most of memtables off heap. > Suspect this will help G1 even more than CMS.
