Having said that, you might also just try, instead:
-XX:+UseParallelGC
-XX:+UseAdaptiveSizePolicy
I think UseParallelGC is default?
I will try the second option.

I didn't think so, but I could be wrong.
It has been the default for quite some time if multiple cores are available.

I don't think that a Minor GC (involving only the new Heap
area) suspends the applications, while a Major GC does.
Not true; a minor GC does suspend the mutator threads, just

If Major GC's are taking place often, then it must mean that despite the

By increasing the space on the new gen alone, you may make Minor

And by specifying fixed sizes for generations, you can upset the balance
