Re: [gentoo-user] 64bit vs 32bit

["Mike Huber" <michael.huber@gmail.com>]

My understanding is that the major advantage of the 64-bit processors
is for memory address space (>4Gigs of virtual memory space without
PAE, technically 48 bits of address space, which is something like
128Terrabytes of addressable memory).

There must be some advantage associated with being able to hold two
long ints in one register (or some such relationship there).  Anyone
know detailed explanations for situations where 64-bit is more/less
beneficial and why?
