> ConcurrentLinkedHashmap get huge on these servers (200 +Mb) 
> There are some CPU related defaults + Some padding that are the source of this, more
discussion at:
> https://github.com/ben-manes/concurrentlinkedhashmap/issues/43
> upgrading to a newer version should remove the padding and reduce memory usage...
> Another thing I noticed that is related, is that LRUCache 
> default initial size is equal with maximum size... which is 1000, would it make more
sense to have a lower default for initialSize? (64)
