 There is a cache used to improve the performance of the metric mapping, that can greatly improvement performance.

+This maximum can be adjusted using the `statsd.cache-size` flag.

 If the maximum is reached, entries are by default rotated using the [least recently used replacement policy](https://en.wikipedia.org/wiki/Cache_replacement_policies#Least_recently_used_(LRU)). This strategy is optimal when memory is constrained as only the most recent entries are retained.
