It should help performance on almost any JVM app, but much more on large heaps. The GC time is lower and multi-threaded but most importantly the "pause time" is low and nearly constant (based on root set size) The old GC's all scaled pause time roughly linearly with heap size. Apps that created a lot of garbage would have all their threads yielded for large amounts of time. Now, essentially, it doesn't matter how much garbage you create. This is awesome because you used to carefully watch how many allocations you made to avoid bad GC times. Now it doesn't matter. Make as much trash as you want and the GC will deal with it
