Based on my changes to the sclo-python spec, I can confirm that passing "-j0" (which autoscales to the number of CPUs +2 to allow for blocking tests) cuts my local RPM build times from just under 40 minutes to just over 15. So I'll use that to speed up the sclo-python bootstrapping builds, and then we can wait for the dist-git move into Pagure and the introduction of https://fedoraproject.org/wiki/Changes/InvokingTests before looking at changing the main build. >> * the `--failfast` option causes the tests to be aborted as soon as >> one fails.

Agreed, especially as it's easy enough to add in to the spec file if you actually want it in a mock build for some reason. >> * there's a `--slowest` flag in recent releases that lists the 10 >> slowest tests in a given run.

One caveat on this option is that it's a relatively recent addition that was never backported to the 3.5 branch, so it's only applicable to builds of 3.6+.
