That is debatable, but in this context you can see them as fairly equal: Out of the box, they will both use all free memory for caching. Since MMapDirectory is tied to the OS caching, having a large non-heap memory allocation should be seen as a good thing: It means that a fair amount of the index is cached. Do not worry about the memory being taken from the system: If you start a another memory-hungry process, the physical memory should be taken from the buffers used by Solr's MMapDirectory.
