But such a base line would also have to be specific to a platform and
a given set of build options.

You assume a linear scalability, but that is not necessarily so. The
ratio between performance indices of different codes could vary
depending on the build option and the underlying OS.
Btw, IME I/O is mostly negligible in Emacs applications, and generally
is not interesting for the issue at hand. Only CPU is important, and
maybe also memory usage.
