With Java 9 or 10 (doesn't remember) it gets a new Pausless GC, too. Not like the Azul one that works even with low Memory. But for high memory stuff.

Their claims about pause times aren't quite as strong as those of Azul, but <100ms pauses for 100GB+ heaps will still be leagues ahead of most GCs. It's probably also be less CPU-efficient than azul's, since it uses forwarding pointers instead of page table trickery. But if you have such a large heap you'll also have many cores. Here's a performance comparison to G1[1]. [0] http://openjdk.java.net/jeps/189 http://openjdk.java.net/jeps/189 [1] https://rkennke.wordpress.com/ https://rkennke.wordpress.com/
