You misunderstand that sentence.
They are referring to the number of updates they can deliver per unit of Google outbound bandwidth, not the amount of time it takes to run that update. The sentence that you elide with ellipses makes this clear:
We want smaller updates because it narrows the window of vulnerability. If the update is a tenth of the size, we can push ten times as many per unit of bandwidth. We have enough users that this means more users will be protected earlier.
- gwern 13y agoThe exact same reasoning applies to applying the patch: if it takes 10 minutes to apply the patch with normal priority, and 30 minutes to apply in the background, then that's another 20 minutes of vulnerability for that user! Geez.
