Why is this faster on 64 bit than 32 bit?

Question

I\'ve been doing some performance testing, mainly so I can understand the difference between iterators and simple for loops. As part of this I created a simple set of tests

Answer 1

The long datatype is 64-bits and in a 64-bit process, it is processed as a single native-length unit. In a 32-bit process, it is treated as 2 32-bit units. Math, especially on these "split" types will be processor-intensive.
