Adaptive Replacement Cache (ARC) 是 IBM 在 2003 年提出的一种自调优、低开销的缓存淘汰算法。本文旨在对 ARC 算法进行概述，探讨其设计原理与机制。在缓存设计讨论中，ARC 算法被选为淘汰策略。本文基于对 ARC 算法的深入理解，分析其在缓存系统中的应用与价值。传统的缓存淘汰策略包括基于最近访问（R...
This article presents a new self-tuning, low overhead algorithm, namely, Adaptive Replacement Cache (ARC). It responds online to changing access patterns, continually balances between the recency and frequency features of the workload, and demonstrates that adaptation eliminates the need for workload...
This article argues that the self-tuning, low-overhead, scan resistant adaptive replacement cache (ARC) algorithm outperforms the least-recently-used (LRU) algorithm by dynamically responding to changing access patterns and continually balancing between workload recency and frequency features. The ARC'...
cache something else, but don’t worry about it, we use the name “Adaptive responsive Cache” in the Oracle ZFSSA world. Go check out: http://www.c0t0d0s0.org/archives/5329-Some-insight-into-the-read-cache-of-ZFS-or-The-ARC.html Ok, VDEVs will come next! Maybe. Steve I'm a ...
In this paper we have proposed an adaptive dynamic cache replacement algorithm for a multimedia servers cache system. The goal is to achieve an effective utilization of the cache memory which stores the prefix of popular videos. A replacement policy is usually evaluated using hit ratio, the ...

In this section, we first describe a general scheme for the simulation algorithm leveraging the segments defined over the population abstraction. The scheme extends the original algorithm we presented in [23]. In subsequent subsections, we present the key improvements, (i) adaptive and approximate ...
As the performance gap between disks and processors continues to increase, dozens of cache replacement policies come up to handle the problem. Unfortunately,most of the policies are static. Nimrod Megiddo etc put forward a low overhead adaptive policy called ARC. It outperforms most of the static...
We propose an adaptive cache coherence-replacement scheme for distributed systems that is based on several criteria about the system and applications, with the objective of optimizing the distributed cache system performance. We examine different distributed platforms (shared memory systems, distributed memo...
