Benchmarks When running tests, installing operating systems, and compiling software for my Ultra 5, I came to the stunning realization that hey, this system is 64-bit, and all of the operating systems I installed on this Ultra 5 (can) run in 64-bit mode.

Praytell, how do you "optimize" for 64-bit processors?

By designing your huge-dataset algorithms around being able to address, day, each cell in a volume reconstruction, instead of using a technique similar to overlays from the old 16-bit days.

Even in "common" tasks like video editing, 32 bit addressing has reached its limits. It's not for nothing that serious file systems have 64 bit off_t's; but it would be cool to be able to mmap() such a file...
