The higher the aggressiveness, the more will be blocked, and the faster the page will load. However, some website functions may not work at all with the medium and high levels.

"Speedafari is a blocker that strips away all it can so you can still load pages even when your connection is crap," Thorin Klosowski of Lifehacker said. Onething that users should not worry about is privacy as Speedafari has no access at all as to what web pages they visit.
