There is an extension command STATS BENCHMRK that can measure performance for alternative versions of jobs.  It does not profile the code, but it interleaves the versions so as to minimize the effect of machine state, and it produces an SPSS-readable dataset of various measures including time, memory, swapping etc.  It's Windows only.

For Python code in particular, the cProfile module, which is part of the Python standard library, is quite easy to use.

That requires win32api to be installed, right? Ha, I just installed that today in the office! I tried STATS BENCHMARK  before, but it should work now.
