Subject [jira] [Commented] (CASSANDRA-7486) Migrate to G1GC by default
Date Tue, 22 Sep 2015 03:07:06 GMT


Ryan McGuire commented on CASSANDRA-7486:

[~benedict] I modified the schedule GUI to allow you to change the version of stress per operation.
Just change the default 'apache/trunk' to 'enigmacurry/stress-report-interval' where I took
your branch and applied a 4G stress heap. If you want to tweak that, you can put your own
branch name in instead. The GC logs have been logged for awhile now, they're wrapped up in
the same tarball as the other logs that you can download.

See this example for how to specify your test:

> 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.  (NB this is off by default but needs to be part of
the test.)
