I've previously profiled pipenv and found it to be slowed down massively due to launching pip for each package it was working on. Unfortunately the maintainers think the progress bar is more important than performance: https://github.com/pypa/pipenv/issues/2207

That's interesting; they actually discuss the issue and talk about parallelizing it, but all you need to do is pass a requirements file to pip.

It would be nice if pip could act more as a base tool and pass information back to a wrapper.
