I assume you mean 16 mb of ram in a 32 gb space, but yes. As app size approaches address space size, lots of things get worse. That said this new generation of only conservatively sweeping the stack has the significant advantage that the stack has remained pretty small (8mb is still the standard stack size), so if you have precise heap scanning the odds of spurious collections from conservative scanning go down a ton.
