Efficient GC collection with large heap of 30 - 100GB

Can Java 7 now handle large heap of 30 - 100GB efficiently without significant GC pause?

Another option is to use Terracotta BigMemory. This is useful if you are storing objects in a big cache in heap. This is not open source but in my opinion, reasonably priced. BigMemory basically allocates object memory outside heap and hence the heap size can be kept to a minimum or medium size.

There are tuning options available, and concurrent GC, but there will still be some pauses during the GC of the tenured generation.
