for my purposes those PRs make it reasonable, even though it remains one of our slowest tests. we can reopen/reuse this issue for any further test_peg_generator performance improvements as needed.
My PR-32338 further reduces the runtime of the test another ~25%.
On my machine, before 85s, after 65s.
