A common strategy to make any system super-performant is Caching. Almost all software products, operating at scale, have multiple layers of caches in their architectures. Caching, when done right, does wonder to the response time and is one of the main reasons why products work so well on a massive scale. Cache engines are limited by the amount of memory available and hence once it gets full the engine has to decide which item should be evicted and that is where an eviction algorithm, like
