TinyLFU+FIFO is in the simulator (https://github.com/ben-manes/caffeine/wiki/Simulator https://github.com/ben-manes/caffeine/wiki/Simulator). However, you'd probably also want the window cache to correct the deficiency outlined in the updated paper (http://arxiv.org/pdf/1512.00727.pdf http://arxiv.org/pdf/1512.00727.pdf). A FIFO version with that isn't in the simulator, but would be easy to add. mutli1 trace - W-TinyLFU: 55.6% - TinyLFU+Random: 53.8% - TinyLFU+FIFO: 48.6% - TinyLFU+LRU: 54.8% - FIFO: 41.0% - LRU: 46.7% FIFO's poor choice of a victim has a big impact, so it doesn't seem promising. A random policy looks like an attractive fit, though.
