Is there a good reason for such a difference?
sage: m=identity_matrix(1000,sparse=True)
sage: v=vector([1]*1000,sparse=True)
sage: time p = v*m
CPU times: user 2.26 s, sys: 0.00 s, total: 2.26 s
Wall time: 2.26 s
sage: v=matrix(1,1000,[1]*1000,sparse=True)
sage: time p = v*m
CPU times: user 0.36 s, sys: 0.00 s, total: 0.36 s
Wall time: 0.37 s
