Depending on the precise workload, a 64-bit program can be slower than the equivalent 32-bit version. However, if the working sets are large, a 64-bit program can be much faster. It's even weirder on Windows, where a 32-bit program running on a 64-bit OS can handle much larger data sets than the exact same program running on a 32-bit OS (CC3+ is such a program).
