Hi Fredrik
Indeed! Packin/unpacking when repeated 1000 times, takes too much time. And
anyway,
we don't need to pack and unpack every time.
```
res = 2*x+1
...: for i in range(1000):
...: res = R.dup_mul(2*x+1, res)
: t1 = clock()
...: res2 = R.dup_mul(res, res)
...: t2 = clock()
...: print(t2-t1)
...:
1.30838489532
: t1 = clock()
...: res2 = R.dup_pack_mul(res, res)
...: t2 = clock()
...: print(t2-t1)
...:
0.579982995987
```
This should be a better comparison between the two methods. So, Kronecker
does outperform
Karatsuba.
Thanks a lot for pointing out!
Regards
Shivam
