With MPB, trying to rebuild all Ruby related packages, I'd hoped I'll get the results much faster.

The problem (to me) seems to be that packages are build in batches (as can be seen in attached screenshot). If there is some build which takes ages (this time it seems to be qt5-qtwebkit) in some batch, nothing else is processed unless that build finishes. But to me, the slow package has probably the lowest importance. I'd rather see the biggest chunk done than to endlessly wait for some package.

Can this behavior be modified? E.g. the batches could overlap slightly or rebatched with low number of tasks still running. Dunno. But this makes MPB / Copr useless for this task.
