Sanne Grinovero commented on HSEARCH-275:
-----------------------------------------

NIOFSDirectory is being selected automatically on systems in which it should perform better, still there are cases in which this implementations is buggy (see Lucene mailing list). It should be nice to be able to really control which impl to use, overriding the automatic decisions.

> # LUCENE-753: Added new Directory implementation org.apache.lucene.store.NIOFSDirectory, which uses java.nio's FileChannel to do file reads. On most non-Windows platforms, with many threads sharing a single searcher, this may yield sizable improvement to query throughput when compared to FSDirectory, which only allows a single thread to read from an open file at a time.
