Show some real world Wheel stats

[ghickman]

Part of "Why Wheels?|" is the speed factor, we should show that.

I'm thinking something like:

• Two requirements.txt, one with pure python packages, one with a mixture (I'm sure we can find one in an existing project).
• Download sources & make wheels (pip install -r requirements.txt --download-cache=sources & pip wheel -r requirements.txt --wheel-dir=wheels)
• Run an install with each one using time.
• Put up a little table with instructions on how to recreate the test for readers.

Testing with a real project's requirements.txt

Setup:

mkdir wheel-test
pip install -r requirements.txt --download=sources
pip wheel -r requirements.txt --wheel-dir=wheels

Sources

mktmpenv
cd ~/Projects/wheel-test
time pip install -r requirements.txt --no-index --find-links=sources
[...]

Wheels

mktmpenv
cd ~/Projects/wheel-test
time pip install -r requirements.txt --no-index --find-links=wheels --use-wheel
