"Conversion program currently compiled"... seems you are rewriting in
Python an already existing program?

By size I presume you mean MHz speed? Obviously not the physical size
of the processor (although the latter allows for more electrons running
wild inside the CPU

Sure: I suggest you make it faster (generic answer for a generic

Yes it is, others have done it for AIX. In case you don't have a C
compiler for your (generic) IBM Mainframe, try installing the gcc
compiler; there must be some "official" installation offered by IBM or
by others. It's possible though that the python executable will be
faster if compiled with the IBM compilers (this is the case for SGI
Irix, MIPSPro-compiled python is faster than gcc-compiled one).

You'll have to search google (and with some relevant
keywords. Then, you might come back with more specific questions.
