Could they be made to share their metadata cache and download only one copy? Bonus points if they could share their cache of downloaded rpm files, too. 4) Why is the metadata so big in the first place? As far as I can tell, it's a small number (3?) of xml files that don't change all that fast. As a simple but rather silly solution, imagine if the repodata XML files were actually in a git repository and the local machine maintained a clone of the git repo. Then it would download deltas and would probably update very quickly indeed. --Andy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
