Mark, To start, the assignment of 6 gig to maxheap and 2 gig to maxperm is working perfectly. I'll expose my ignorance here and ask about that 80%. Is there some inefficiency in jvm ram assignment in 64 bit in comparison to 32 bit? Is there more overhead in ram assignment? Just wondering what's up with the difference.
