Why generators take long time?

I was playing with Generators and found that using Generators time is bit more than list-comprehensions or I am doing it wrong?
Function with List comprehensions:
def sum_text(number_range):
return sum([i*i for i in xrange(number_range)])
%timeit sum_text(100000000)
1 loops, best of 3: 14.8 s per loop
Using generator Expressions:
def sum_text(number_range):
return sum((i*i for i in xrange(number_range)))
%timeit sum_text(100000000)
1 loops, best of 3: 16.4 s per loop
