------------------------------------

The above should reference a 10% improvement over LRU, not LFU. Sorry.

> Quote from Mircea Markus:
> There is an eviction policy algorithm more efficient than LRU (which I found quite popular) - Adaptive Replacement Policy. The basic idea is to not rely only on the time of last access to the node, but also on the number of time(frequency) a given node was accessed. Here it is a nice description of how it works: http://en.wikipedia.org/wiki/Adaptive_Replacement_Cache.
