The plugin seems to have no documentation (at least in the package) so it's hard to interpret what's going on without reading the code. > So - on the original subject. With fastestmirror out of the list- how > are your result times from yum? # time yum update Loaded plugins: protectbase, refresh-packagekit 0 packages excluded due to repository protections Setting up Update Process No Packages marked for Update real 0m4.861s user 0m3.731s sys 0m0.291s # I also repeated the test on Ubuntu: $ time sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: linux-headers-generic linux-image-generic 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded. real 0m0.931s user 0m0.444s sys 0m0.056s % So yum is now only 5 times slower than apt-get (real time) rather than 10 times as before. Of course without the fastestmirror plugin I risk downloading from a slow mirror when I actually do a non-null update. poc -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
