For sympy I am getting:
In [1]: var("a b c x y z")
Out[1]: (a, b, c, x, y, z)
In [2]: %timeit (3*(a*x + b*y + c*z)).expand()
10000 loops, best of 3: 128 µs per loop
and for sympycore I am getting:
In [8]: %timeit (3*(a*x + b*y + c*z)).expand()
10000 loops, best of 3: 199 µs per loop
So sympy actually seems faster than sympycore.

Pearu probably has some comments.

I think sympycore doesn't use caching. For sympy, it's described here:
