Phil Yang commented on CASSANDRA-7486:
--------------------------------------
Another small question :)
Since many performance improvements were made to G1 in JDK 8 and its update
releases, do we need to have a propose for jdk7 users especially its early
versions to update to jdk8's latest version?
And I find a JEP that "Make G1 the default garbage collector on 32- and 64-bit
server configurations." in jdk9. See http://openjdk.java.net/jeps/248 if you
have not heard about it.

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