Performance of the new resolver when installing/upgrading many packages at once

See original GitHub issue

What did you want to do? I liked to use

pip list --outdated --format freeze | sed 's/==.*//' | xargs --no-run-if-empty pip install --upgrade --upgrade-strategy eager

to update all packages. However, this updates packages beyond the requirements of installed packages, which pip ignores, leading to conflicts.

Same thing even for

pip list --format freeze | sed 's/==.*//' | xargs --no-run-if-empty pip install --upgrade --upgrade-strategy eager

Now, the new resolver looks promising in the second case (it still ignores installed packages, so --outdated is not an option, but that’s not too much of an issue):

pip list --format freeze | sed 's/==.*//' | xargs --no-run-if-empty pip install --upgrade --upgrade-strategy eager --use-feature=2020-resolver

It upgrades only what’s possible to upgrade without causing conflicts, and even downgrades what’s required to resolve conflicts. It’s basically a one-stop-shop to fix a set of installed packages. Nicely done!

However, it’s slow:

  • pip list --outdated takes ~15s
  • pip list | sed | xargs pip install takes ~9s with the old resolver (in its 2nd run when all package installation have finished), but it takes ~55s with the new resolver (again, in its 2nd run without package installation)

I’m surprised that pip list | sed | xargs pip install is faster than pip list --outdated because I expect the latter to do much more than the former, but that’s not what I am worried about. But note how much slower pip list | sed | xargs pip install is with the new resolver. I first suspected additional (repeated) HTTP requests for the same packages as an issue, but

pip list --format freeze | sed 's/==.*//' | xargs --no-run-if-empty pip install --upgrade --upgrade-strategy eager --use-feature=2020-resolver -v | grep GET | sort

shows the same (125) requests as

pip list --outdated -v | grep GET | sort

--outdated is slower here also because all the requirements are already installed. Those on-disk installation can be re-used directly; --outdated, by contrast, needs to make additional queries to know whether the installed version is outdated or not, and thus slower.
