We consider the cell probe complexity of the polynomial evaluation pro
blem with preprocessing of coefficients, for polynomials of degree at
most n over a finite field K. We show that the trivial cell probe algo
rithm for the problem is optimal if K is sufficiently large compared t
o n. As an application, we give a new proof of the fact that P not equ
al incr-TIME (o(log n/log log n)).
