Jonathan Shook commented on CASSANDRA-10403: -------------------------------------------- Can we get some G1 tests with a 24+G heap to see if it's worth making this machine-specific? The notion of "commodity" changes with time. The settings need to adapt if possible. > Consider reverting to CMS GC on 3.0 > ----------------------------------- > > Key: CASSANDRA-10403 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10403 > Project: Cassandra > Issue Type: Improvement > Components: Config > Reporter: Joshua McKenzie > Fix For: 3.0.0 rc2 > > > Reference discussion on CASSANDRA-7486. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
