In a 64 bit VM, will using longs instead of ints do any better in terms of performance given that longs are 64 bits in java and hence pulling and processing 64 bit word may be faster that pulling 32bit word in a 64 bit system. (I am expecting a lot of NOs but I was looking for a detailed explanation).
EDIT: I am implying that "pulling and processing 64 bit word may be faster that pulling 32bit word in a 64 bit system" because I am assuming that in a 64 bit system, pulling a 32 bit data would require you to first get the 64 bit word and then mask the top 32 bits.
