Kým som používal 32bit Linux, tak som sa s aplikáciami čo bežne používam cez 1GB ani nedostal, na 64bit stále striehnem, aby som neprešvihol 2GB, pretože to začne swapovať.Tady mám nutkání říct [citation needed], imho ta náročnost na paměť stoupla se stoupajícími nároky aplikací, ne s přechodem na 64-bit...
The main disadvantage of 64-bit architectures is that, relative to 32-bit architectures, the same data occupies more space in memory (due to longer pointers and possibly other types, and alignment padding). This increases the memory requirements of a given process and can have implications for efficient processor cache utilization. Maintaining a partial 32-bit model is one way to handle this, and is in general reasonably effective. For example, the z/OS operating system takes this approach, requiring program code to reside in 31-bit address spaces (the high order bit is not used in address calculation on the underlying hardware platform) while data objects can optionally reside in 64-bit regions.
