Test run seriously slowing down when renaming contracts folder

[alexykot]

• Populus Version: 1.11.0
• OS: linux/ubuntu
• Python 3.5.2 (default, Sep 14 2017, 22:51:06)

What was wrong?

consider folder structure:

contracts/
tests/
project.json
README.md

tests folder has 52 items to run, running them all with command py.test -s --disable-pytest-warnings --populus-project=./ ./ takes ~85 seconds, maxing out load on one CPU core on my old laptop.

Now consider this folder structure:

ws_contracts/
tests/
project.json
README.md

Same files inside, project.json amended to reference the right folder. Running same tests with the same command takes 4-5 times longer, also maxing out load on one CPU core on my old laptop. No apparent reason why.

Expected: renaming the contracts folder should not affect the test running time.

I've tried this with the populus init-made Greeter project, and noticed that the ws_contracts test run, executed as plain py.test, produces several times more deprecation warnings. The "extra" ones seem to be mostly:

/home/veox/src/populus-greeter/.virtualenv/populus-greeter/lib/python3.6/site-packages/eth_utils/functional.py:21: DeprecationWarning: The `compose` function has been deprecated and will be removed in a subsequent release of `ethereum-utils`.  It is recommended that you switch to use a library like `cytoolz` which provides similar functionality through the `cytoolz.functoolz.compose` function.
    "The `compose` function has been deprecated and will be removed in a "

(The trunctation of the second line appears in both contracts and ws_contracts run; and for other warnings, too.)

Consider comparing the generated warnings (that you currently discard). These may point to the root of the issue.

EDIT: Actually, the fact they're more numerous may itself highlight the cause.

EDIT: Posted wrong DeprecationWarning at first.

BTW, which Python version are you running?

[alexykot]

Python 3.5.2 (default, Sep 14 2017, 22:51:06). Added to the issue description.

Yes, I discard general warnings because they point to all issues in all dependencies that is not really helpful, and as you see there is a lot of them. I'll check that though.
