Albert P Tobey commented on CASSANDRA-7486:
-------------------------------------------

I managed to get G1 (Java 8) to beat CMS on both latency and throughput on my 
NUC cluster.

Preliminary results: https://gist.github.com/tobert/ea9328e4873441c7fc34

> 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.)
