You need to define a polynomial ring: sage: P.<x> = PolynomialRing(RR) sage: f=x^24+34*x^12+45*x^3+9*x^18 +34*x^10+ 32*x^21 sage: time for i in range(10000): a=f(x=RR.random_element()) CPU times: user 0.31 s, sys: 0.00 s, total: 0.31 s Wall time: 0.32
sage: def g(y): ....: return y^24+34*y^12+45*y^3+9*y^18 +34*y^10+ 32*y^21 ....: sage: time for i in range(10000): a=g(RR.random_element()) CPU times: user 0.83 s, sys: 0.02 s, total: 0.85 s Wall time: 0.86 In your example, x is a symbolic (== slow) variable. If you define your polynomial ring first things are much faster.
