It is designed to be both effective and straightforward, using only one queue and one pointer called "hand" to maintain the insertion order between objects. The algorithm tracks the visited/non-visited status of each object in the queue using a single bit and makes decisions based on this status. SIEVE has been shown to outperform state-of-the-art eviction algorithms in terms of efficiency, demonstrating significant reductions in miss ratio across diverse datasets.
However, it is important to note that SIEVE is not scan-resistant, particularly in block cache workloads, where it may show a higher miss ratio than LRU due to the lack of a ghost cache to track recently evicted items. Despite this limitation, SIEVE's performance and simplicity make it a compelling choice for many caching systems.
