For a very unscientific comparison, it takes about 1m 40 sec for yum-3.2.23-3.fc10.noarch (with --disableplugin=*) to do the same. for yum: $ echo n|time sudo yum --disableplugin=* update 92.13user 6.77system 1:39.82elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+8720outputs (0major+74159minor)pagefaults 0swaps for solv: $ echo n|time sudo solv update 0.48user 0.05system 0:01.53elapsed 34%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+7633minor)pagefaults 0swaps so there is a 50x speed difference in favor of solv. -- Jussi Lehtola Fedora Project Contributor jussilehtola@xxxxxxxxxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
