RPM and Yum Enhancements

Summary

We feel the need - the need for speed.

  • Speed up resolving below 2 minutes (better below one minute) in worst case (on a reasonably new computer)
  • Reduce memory consumption significantly below 100MB for most cases - may be even for all cases

Owners

  • Owners: JeremyKatz, SethVidal, PaulNasrat, FlorianFesti

Current status

  • Targeted release:
  • Last updated: 2007-12
  • Percentage of completion: 90%
  • Things look much better now.

Detailed Description

Profile the rpm/python/yum stack. Find the hotspots. Fix them. Discussions at the following threads.

thl: Maybe also get rid of file deps outside of /etc, /bin, /sbin, /usr/bin, or /usr/sbin in our packages as much as possible, too, as they sometimes slow down yum's depsolving a lot? The Packaging Committee has something in the queue , but there is not much interest to drive it forward afaics.
