Java G1 garbage collection in production

Question

Since Java 7 is going to use the new G1 garbage collection by default is Java going to be able to handle an order of magnitude larger heap without supposed \"devastating\" G

Answer 1

I'm working with Java, for small and large Heap, and the question of the GC and Full GC appears every day, as the constraints may be more strict than others : in certain environment, 0.1 second of scavenger GC or Full GC, kill simply the fonctionnalité, and have fine grained configuration and capability is important (CMS, iCMS, others ... the target is here to have the best possible response time with the nearly real time treatment (here the real time treatment is often 25 ms ), so, basically, any improvements in GC ergonomy ans heuristique are welcome !
