Magit is very slow with Guix's Git checkout

Magit is very slow with Guix's Git checkout

Hi,

I've been learning to use Magit more and more, and I really enjoy it.
However, I've noticed that it takes a very long time (minutes) to give
control back to me when I run "M-x magit-status" in my Guix checkout.

Am I doing something wrong?  Is there a way to avoid this slowdown?
Magit is great, but it's painfully slow when I try to use it to interact
with the Guix's Git repository.

Apparently issues like https://github.com/magit/magit/issues/3808 are
being systematically closed in favor of a plan to compute diffs in two
steps.  However I don't entirely understand the argument as magit-status
on a clean tree should be free.  I share the frustration.

This is probably due to the po directory containing lots of changes. I
normally get rid of these changes, as I never intentionally changed
anything in that directory. Magit is probably slow as it's rendering the
diffs for large files, so I'd watch out for what changes you have in the
repository if Magit is slow.

Run “git checkout -- po” to undo the automatically generated changes to
the “po” directory, which in my experience is responsible for the slow
down.
