Comment 6 jcallaha 2017-06-01 14:04:44 UTC
Verified in Satellite 6.2.10 Snap 2.

I tested this on 5 total products, all of which were aligned to 25k content hosts. The time it took for changes to individual repositories varied from 2 to 8 seconds. The average completion time was right around 6 seconds.
