Hi! Here is a first ticket, with patch: http://trac.sagemath.org/sage_trac/ticket/7578
It reduces the computation time of the original example of this thread to the time that is needed to convert the underlying finite polynomials. Hence, as long as the conversion does not improve, it seems to me that the arithmetic of the infinite polynomials can not be further improved. Or, positively: There seems to be considerable room for improving the polynomial conversion, and the infinite polynomials would directly profit from any progress. But this should be a different ticket.
