Which iOS Content Blocker is the Fastest?
When I tried with all blockers on, I did not get the performance of the fastest blocker, and instead got performance on the slower side of the blockers tested. It is my recommendation that you only use one blocker at a time.

As you can see, 1Blocker is the winner. It was (on average) 61.83% faster than having nothing turned on at all. That’s staggering. The worst of the lot seems to be Vivio, which was marginally faster than simply just turning on ‘Do Not Track’ in your browser settings.
1Blocker is also highly configurable as well. If you want something on the simple end of things, which makes decisions for you to unblock ads from places like The Deck, Adamant is a great option. It was the third fastest overall, and is trying to support the indie sites ad revenue the best it can.
