Uwe Schindler resolved LUCENE-753. ---------------------------------- Resolution: Fixed This issue was resolved a long time ago, but left open for the stupid Windows Sun JRE bug which was never resolved. With Lucene 3.x and trunk we have better defaults (use e.g. MMapDirectory on Windows-64). Users should default to FSDirectory.open() and use the returned directory for best performance. > Use NIO positional read to avoid synchronization in FSIndexInput > ---------------------------------------------------------------- > > Key: LUCENE-753 > URL: https://issues.apache.org/jira/browse/LUCENE-753 > Project: Lucene - Java > Issue Type: New Feature > Components: Store > Reporter: Yonik Seeley > Assignee: Michael McCandless > Attachments: FileReadTest.java, FileReadTest.java, FileReadTest.java, > FileReadTest.java, FileReadTest.java, FileReadTest.java, FileReadTest.java, > FileReadTest.java, FSDirectoryPool.patch, FSIndexInput.patch, > FSIndexInput.patch, LUCENE-753.patch, LUCENE-753.patch, LUCENE-753.patch, > LUCENE-753.patch, LUCENE-753.patch, lucene-753.patch, lucene-753.patch > > > As suggested by Doug, we could use NIO pread to avoid synchronization on the > underlying file. > This could mitigate any MT performance drop caused by reducing the number of > files in the index format. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
