Subject Re: solr-5.2.1: All folders in solr box(Linux) are sitting in RAM

Why do you want to avoid this? Having the index in RAM (either the JVM or OS)
is essential to fast querying. Perhaps you're being mislead by the
MMapDirectory's
consumption of the OS memory? See Uwe's excellent article here:
