Change default Directory impl on 64bit linux to MMap
----------------------------------------------------

                 Key: LUCENE-3198
                 URL: https://issues.apache.org/jira/browse/LUCENE-3198
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Michael McCandless


Consistently in my NRT testing on Fedora 13 Linux, 64 bit JVM (Oracle 1.6.0_21) I see MMapDir
getting better search and merge performance when compared to NIOFSDir.

I think we should fix the default.
