That wasn't about "poor" as in slow vs. "great" as in fast but
bandwith capped vs. not.

If building deltas are slow the solution is not to disable them but to
find out why there are slow and fix that. One thing for instance is
that it insists on generating the original rpm while creating an
uncompressed rpm would save a compress + uncompressed cycle during
updates (the former is a bit extensive for xz).
