      Description

      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)
