Bryan Cantrill surveys caching strategies and explains the design of the Adaptive Replacement Cache algorithm.
Bryan Cantrill on "ARC: A Self-Tuning, Low Overhead Replacement Cache" by Nimrod Megiddo and Dharmendra Modha ( usenix.org/legacy/event/fast03/tech/full_papers/megiddo/megi… ) Bryan Cantrill is the CTO at Joyent, where he oversees worldwide development of the SmartOS and SmartDataCenter platforms, and the Node.js platform. Prior to joining Joyent, Bryan served as a Distinguished Engineer at Sun Microsystems, where he spent over a decade working on system software, from the guts of the kernel to client-code on the browser. In particular, he co-designed and implemented DTrace, a facility for dynamic instrumentation of production systems that won the Wall Street Journal's top Technology Innovation Award in 2006 and the USENIX Software Tools User Group Award in 2008. Bryan also co-founded the Fishworks group at Sun, where he designed and implemented the DTrace-based analytics facility for the Sun Storage 7000 series of appliances. Bryan received the ScB magna cum laude with honors in Computer Science from Brown University.Why it's here

On “Sieve is simpler than LRU”
> it seemed natural to have a set of generations for items that have only been seen once, and then another generation for things that have been more active Have you looked at ARC? It sounds similar - it is a cache split between LRU and MFU areas, where the split point changes dynamically depending on the workload. link to this video is a fun watch on the topic.

On “ZFS on Linux still has annoying issues with ARC size”
The author calls ARC autotuning “opaque” which surprised me given a well regarded paper has been published on it: link link to this video ...that said the author has been writing on the ARC for more than 10 years judging from his blog links so perhaps that paper did not answer his questions.
