To use a current example, the updates/x86_64/Packages directory for CentOS 6.5 is 873MB, while the drpms directory is 8.2GB (almost 10x the rpm size). In comparison, the packages in the updates directory for Fedora 20 use roughly 10GB, while the drpms directory is only 2.4 GB. (roughly 1/4 the rpm size). Rather than completely ditching drpms, I'd suggest pruning the old drpms. Jonathan
