Hello I'm (still) trying to figure our high memory usage by PRT. I have studied heapRegionRemSet.cpp code and came up with a calculation I need you to confirm. Given region size of 8M and default G1 settings: * max number of PRT instances is 2^12 for each HR * PRT size is 64MB
I'm looking at the worst-case scenario and I don't dare to multiply the tree numbers. The cap is just to high. Am I missing something? Do only Young HR get a OtherRegionsTable? Where can I find the number of regions per generation? I cannot spot it in GC logs.
