Roughly, yes. Though assembly of residuals and Jacobians is still your
business and its performance will vary greatly with the class of method and
your implementation.
Apologies if this question is too basic, I'm just trying to understand
what I would be sacrificing if I chose to completely write my
application on Python.

Hello,
I'm wondering if any performance studies have been conducted between
codes written using PETSc on C versus Python implementations using
PETSc4py. Other than this, I'd really appreciate it if someone can
give
perspectives on the drawbacks/advantages on opting for either for
code
development.
No PETSc code is in Python, so there is no difference as long as you
do not call PETSc
function millions of times from Python. It should always be possible
to operate at the right
granularity.
Thanks,
Matt
