Holding processor speed constant, I don't think there's much difference
among 32-bit processors or OSes.

I don't know exactly how 32-bit versus 64-bit mode affects PLT Scheme
performance, but the new JIT compiler works for 32-bit systems, only.
That will change when I have regular access to a 64-bit system.

PLT Scheme can use more than 4GB on a 64-bit system (but only 4GB on a
32-bit system, of course).

PLT Scheme currently can't take much advantage of multiple processors,
except to the extent that the OS does automatically (e.g., to serve
non-blocking I/O requests on the other processor for MzScheme). This is
something that we'll likely work on, though, over the new few years.
