Comment(by ylchapuy):
for the record:
{{{
sage: m=random_matrix(ZZ,1000,sparse=True,density=0.01)sage:
m=random_matrix(GF(17),1000,sparse=True,density=0.01)
sage: v=vector([randrange(100) for i in xrange(1000)])
}}}
before:
{{{
sage: timeit('m*v')
5 loops, best of 3: 257 ms per loop
}}}
after:
{{{
timeit('m*v')
5 loops, best of 3: 61 ms per loop
}}}
