Comment (by mabshoff):
One more data point to the above remark malb did. With the patch applied:
{{{
sage: n = 296
sage: P = PolynomialRing(GF(2),n,'x')
sage: v = vector(P,100)
sage: A = matrix(P,100,100)
sage: %time _ = A*v
CPU times: user 0.04 s, sys: 0.00 s, total: 0.04 s
Wall time: 0.04 s
sage: %time _ = A*v
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
}}}
So there is more than an order of magnitude improvement here :)
Cheers,
Michael
