Investigate relatively slow lock generation #1251

Closed SmileyChris closed 2 years ago

SmileyChris commented 2 years ago

A colleague put this Python package manager shootout together very recently.

While there are "Lies, damned lies, and statistics", it is interesting that the relative lock generation speed is much slower than the other tools. Is pdm doing a more thorough job in creating the lock? Is it's dependency graph generation slower? Maybe the shootout is just doing something incorrectly?

An area of improvement to look into, in any case...

Did you see the latest test result: https://github.com/lincolnloop/python-package-manager-shootout/actions/runs/2708687120 It is updated due to a cache not clean issue of Poetry. And also notice the thorough run time, you will get a different conclusion.

@frostming I have been seeing slow locking issues as well on 2.18.1. May I ask what is the dependency resolution algorithm used by pdm? Is it pubgrub or something else?
