Comment (by SimonKing):
The following is on top of sage-5.2.beta3 plus #12313 and its
dependencies.
When I remove the custom is_subcategory method in
covariant_functorial_constructions.pyx, and apply
[attachment:trac_13400_subclass_hook_cython.patch], I get
{{{
sage: def test1(N,B,t):
....: for i in range(t):
....: m=matrix(QQ,N,N,srange(N*N)).echelon_form()
....:
sage: %time test1(20,40,10^3)
CPU times: user 7.04 s, sys: 0.06 s, total: 7.09 s
Wall time: 7.11 s
}}}
When I apply my patch but keep the covariant functorial constructions as
they are, I get
{{{
sage: def test1(N,B,t):
....: for i in range(t):
....: m=matrix(QQ,N,N,srange(N*N)).echelon_form()
....:
sage: %time test1(20,40,10^3)
CPU times: user 7.38 s, sys: 0.06 s, total: 7.44 s
Wall time: 7.45 s
}}}
When I do nothing on top of #12313, I get
{{{
sage: def test1(N,B,t):
....: for i in range(t):
....: m=matrix(QQ,N,N,srange(N*N)).echelon_form()
....:
sage: %time test1(20,40,10^3)
CPU times: user 7.58 s, sys: 0.03 s, total: 7.60 s
Wall time: 7.63 s
}}}
Again, it isn't exactly a break-through. I didn't time it pre-#12313, yet.
