Thankfully there are better algorithms that are not encumbered. ARC is fairly memory hungry and requires a large cache to be effective. It is not as scan resistant and does not capture frequency as well as many believe. LIRS or TinyLFU based policies are what new implementations should be based on. https://github.com/ben-manes/caffeine/wiki/Efficiency https://github.com/ben-manes/caffeine/wiki/Efficiency
