>                 Key: CAMEL-8994
>                 URL: https://issues.apache.org/jira/browse/CAMEL-8994
>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-core
>    Affects Versions: 2.14.3
>            Reporter: Zoltan Farkas
>
> 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)
