32-bit and 64-bit performance comparisons

In most cases, running 32-bit applications on 64-bit hardware is not a problem, because 64-bit hardware can run both 64-bit and 32-bit software. However, 32-bit hardware cannot run 64-bit software.

To find out if any performance issues exist for applications that are running on the system, refer to those application's user guides for their recommended running environment.
