Our tests clone our repo 40+ times for each PR commit (and some PRs have dozens of commits)

[Ark-kun]

And the real number is much higher due to test failures and re-runs.

Prow pulls our repo for each test suite (we have 5+).
Our test workflows pull the code to build images (24 times). Most of those come from sample tests.
Our test runners then pull the code again before running (11 times). For some reason we only put a single run_test.sh script in test images and not all the required code.
