  1. Make a manual comparison Brave (without AdBlock) vs Brave(with AdBlock) vs Chrome (+uBlock) in terms of memory, CPU usage, and browsing speed;
  2. Enable reward in some perf test configuration (=Adblock code should be covered by perf tests).

If you create all of 6k in the test set it consumes 1Gb. Trying to investigate why and find an alternatives.
