--- Comment #3 from Mark Johnston <markj@FreeBSD.org> ---
If I am reading the output correctly, we are spending hundreds of ms copying
page tables, but this is not where the majority of time is spent.

It would also be useful to see output from

# dtrace -n 'profile-997hz /pid =3D=3D $target/{@[stack()] =3D count()}' -c=
 "python
test.py"
