Replaced with a count of the map.</p> <p>Secondly, (apply f anything) is slow. Profiler showed that the (apply min-key) was really slow. This is mitigated by using a c.d.priority-map instead. On a priority-map, (ffirst {}) or (first (peek {}).</p> <p>Also inverted the logic for threshold comparison. Since there is a (build-leastness-queue) that populates statistics, should caches should favor codepaths for the state of being full all the time?</p> Mac Oracle JDK, Linux OpenJDK CCACHE-27

Missing LU and LRU is linear complexity - performance

I think it's more the fact that it's doing a linear scan on keys every single time.</p> <p>(apply) does show up a lot in a profiler, but I haven't figured out why. (apply + (range big)) seems to even be slightly faster than (reduce +) on the same range.</p> <p>Patch in proper format</p> Global Rank Patch Code http://dev.clojure.org/jira/browse/CCACHE-22 core.cache <p>"limit" is used in other caches to represent quantity, for TTL it represents time.

Change limit parameter name in TTLCache
