> Hello,
> Currently LRUMap uses maxSize parameter to configure its maxSize.
> This is not great for its memory usage.
> For example I have a use case where I can't really guess the target maxSize of LRUMap
so I have put a big number .
> In reality I end up having 380 elements but LRUMap uses 33 Mb of memory because it allocates
(as capacity) LOAD_FACTORxsupposed max size.
> It would be nice to have the possibility to set maxSize apart making it unrelated to
capacity.
