Fun talk on adaptive LRU/MFU cache
> 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. this video is a fun watch on the topic.
Linked alongside paper on ARC autotuning
The author calls ARC autotuning “opaque” which surprised me given a well regarded paper has been published on it: link 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.
