Not only faster, but we aren't beholden to the APIs offered by Google and others. Manifest v3 threatened the existence of popular content-blockers like uBlock Origin. Since we are the browser, we aren't so limited. A recent example of how we are able to do more was with the introduction of CNAME blocking, which allowed us to identify when a third-party tracker had managed to be requested from a first-party URL: https://brave.com/privacy-updates-6/.
Hey, thanks. One of my favorite computers is a Surface 3 running a Cherry Trail CPU. I tried Brave out and it's noticeably snappier on the old hardware than Firefox or Chrome.
uBlock Origin is using Web Assembly now for certain critical code. Anyway performance differences between the two have always been negligible and often fluctuating.
