Josh McKenzie commented on CASSANDRA-18027:
-------------------------------------------
bq. Benchmarks show that G1 and Cassandra work best when objects are promoted
immediately
Curious - were those in-memory max throughput, or fixed velocity latency, or
spilling over to disk dealing with large workloads?
And to be clear, +1 on the general sentiment of what you're doing here and this
ticket. I'm just noodling on how we benchmark things as a project historically
and whether there'd be value in clarifying when and how we benchmark different
things; well outside the scope of this ticket (as is my apparent habit - sorry
=/)

> G1GC is well battle tested now, and the recommended configuration for most
> users. CMS can work well on smaller heaps but requires more tuning, initially
> and over time. G1GC just works. CMS was deprecated in JDK 9.
