Should NIOFSDir use direct ByteBuffers?
---------------------------------------
Key: LUCENE-2056
URL: https://issues.apache.org/jira/browse/LUCENE-2056
Project: Lucene - Java
Issue Type: Improvement
Components: Store
Reporter: Michael McCandless
Priority: Minor
I'm trying to test NRT performance, and noticed when I dump the thread stacks that the darned threads often seem to be in {{java.nio.Bits.copyToByteArray(Native Method)}}... so I wondered whether we could/should use direct ByteBuffers, and whether that would gain performance in general. We currently just use our own byte[] buffer via BufferedIndexInput.
It's hard to test since it's likely platform specific, but if it does result in gains it could be an easy win.
