I have taken Zing for a spin on 24 c3.8xl ec2 instances running Elasticsearch with 32G heaps and just under 2 billion indexed documents with millions of updates/day. The results are considerably better. If I just went up to 30 or even 50 ec2 instances on HotSpot/Openjdk, I would see no performance benefit with regard to GC. And I have performed this test. I'm not saying dont use Java because of GC, but I am saying don't overestimate the value of more efficient garbage collection in any case.

Shoutout to the Azul guys, Simon, Elaine and Paul for coming on-site and watch me compile all their extensions on Amazon Linux and help me perform all the testing.
