You may want to look at using GMPY. GMPY wraps the Gnu Multiple-
precision library and includes support for rational arithmetic. I just
tested a few calculations involving rational numbers with hundreds to
thousands of digits and GMPY's mpq type was between 10x and 100x
faster than fractions.Fractions.

GMPY is availabe at http://code.google.com/p/gmpy/
