I'd like to see some data indicating there is actually an appreciable performance difference. Indeed, with only one line of code to add, the setup cost is low, but this article asserts a performance gain without any evidence.
You may want to disable this in production
for a significant performance boost
I'm inclined to believe the engineers who wrote the docs on this.
It's a great tool to have in your belt for optimizing angular apps, most people working with angular are not aware of this unfortunately.
That said, I'm not sure it made much perceptible difference as the app already performed adequately and the reduction is amortized across all of the interactions the user makes.
