   I'm porting my application from .Net framework/Lucene 3.0.3 to .Net 7/Lucene 4.8.0.
   After several single thread/multithread tests I discovered that using of SimpleFSDirectory is almost 2 times faster than MMapDirectory. 
   Index size is ~ 150Mb
   JetBrains dottrace shows that most of time is spent by MMap related stuff.
