@markap14 what do you think about using
https://github.com/ben-manes/caffeine instead? They have benchmarks showing
performance difference from current approach (named `LinkedHashMap_Lru`). Take
a look at probably the most important _Read 100%_ scenario. If you want, I can
also rewrite other `LinkedHashMap` usages for cache? `grep removeEldestEntry`
shows 10 other places.---
