alt Hacker News> dnf < 5 was still performing similarly to yum (and it was also implemented in python)
I'm perhaps not properly understanding your comment. If the algorithmic changes were responsible for the improved speed, why did the Python version of dnf perform similarly to yum?
Because dnf4 used the same dependency resolution as yum but they revamped it in dnf5 (it was initially supposed to be a whole new package manager with a different name)
