I've been using various ad blockers, including AdGuard, and recently started worrying about these extensions potentially degrading my browser's performance. To investigate further, I ran Safari benchmarks using Speedometer 3.0 with different ad blockers enabled and noticed that some of them can significantly reduce performance. As a result, I decided to remove all ad-blocking extensions and switched to using AdGuard's DNS ad blocker instead. However, the downside is that I can't use Private Relay with this setup. Now, I'm considering switching back to using Private Relay along with ad-blocking extensions, or possibly using a VPN that has DNS ad-blocking capabilities.
