So you are running on a niagara type cpu (T1, T2, ...). These are cpus with a lot of cores and threads but with limited single thread power. When you say, it is an old application, then it is most likely a single threaded one and not very well suited for such an architecture (or vice versa).

Recompiling in 64 bit mode could speed up things a little, if there is a lot of 64 bit arithmetic going on in the program. But I would not expect to much from this step.
