<@U051221NF> Arbitrary test run here, I think this was `typing_test.py` - which has no real dependencies.
I don't think any of it is symlinked (but haven't checked)
``` T/pants-sandbox-oTq2tt % du -h -d 1 
2.6M    ./requirements.pex
 20K    ./.pytest_cache
  0B    ./extra-output
940K    ./local_dists.pex
4.0K    ./__pycache__

⏺ T/pants-sandbox-oTq2tt % ```

That's obviously with the sandbox flag, so not 1:1 - but that source code should be like... 2 files

Degenerate test example:
pytest on that file - 0.3s
pants test (after first run completed): 1.7s

Just FYI - I was going to put eyeballs on this as an upcoming perf win in a couple weeks, but if you're already rooting around rule runner - and if there is anything obvious :shrug:
