I haven't used it, but based on a reading of their blurbs, I suspect
you won't see any significant improvement in base Python code - the
advantage is the numeric computation work.

For general Python performance, check out PyPy, although it tends to
lag behind CPython in versions somewhat. However, PyPy doesn't do
anything for your numpy performance, and doesn't even guarantee that
everything works:

http://pypy.org/download.html#installing-numpy

So if the Intel Math Kernel Library lives up to the descriptions, it
might be the thing to fill in this gap - "use PyPy to speed up your
Python code, or Intel Python to speed up your numpy code". (Most
programs won't have performance issues on both of those at once.)

It's worth noting that Intel engineers have been proposing a number of
performance improvements for backporting into the CPython core, and
some of them even made it into 2.7. I've no idea whether the page you
linked to is part of the same project or not; it might be completely
separate, or it might be the source of all those improvements.
