A three level page table is good enough for systems with less than 3.8TB of memory, for bigger systems four page table levels need to be used. Each page table level costs a bit of performance, use 3 levels for normal systems and 4 levels only for the really big systems. To avoid bloating sparse.o too much set MAX_PHYSMEM_BITS to 46 for a maximum of 64TB of memory.
