[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-275) support new NIOFSDirectory, a multithreaded optimized FSDirectory

[Sanne Grinovero (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31536#action_31536 ] 

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

it appears that to enable this FSDirectory variant a system propery has to be set (just as for MMapDirectory)
which will change the behaviour of existing FSDirectoryProvider.
Should we parse this property from the configuration and set it, or just document the system property to be set?
(in the latter case, no change is needed to the code, besides docs)

> # 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.
