Building a system 64-bit buys you: |
7 |
- wider integers (so math with 64-bit integers is faster) |
8 |
- wider pointers (so an application can have a *lot* more address space |
9 |
allocated to it) |
10 |
- bigger binaries and data structures (so more RAM consumed) |
11 |
- future-proofing (in a few years, 32-bit hardware will not be |
12 |
available new) |

There's no "better" and it's not inherently faster in any way. As |

another poster said, most UNIX apps have been running 64-bit on other |
16 |
architectures (SPARC being the most common) for years, so compatibility |
17 |
isn't a big deal. |

Those are the points on which I base my 32/64 decisions. |
