Re G1GC in Java 9, yes it's the default, but we explicitly specify the collector when we start Cassandra.
Regarding load testing, some folks like cassandra-stress, but personally I think second to production itself, there's nothing better than an environment running the full applications stack with simulated load. Yes, it's a lot of setup, but imo it's necessary for any sort of performance / acceptance testing.
