Subject MMapdirectory Configuration
Date Tue, 16 Dec 2014 16:02:52 GMT
Finally we are seeing great improvement once we switch to 64-bit java and
MMapDirectory. Our Test run (multiple requests) used to take 26 minutes on
32-bit and is now improved to 10 minutes on 64-bit java.

We load stored documents from lucene and pass the documents to a third
party libray (closed source) for further processing (Note: we can not
utilize inverted index for this processing).  The third party library is
memory intensive and it needs around 10GB of heap memory for our load. We
have a cap of 16GB system memory available and our index is of 8GB in size

note: sorry for the repost. There was an issue with formatting earlier and
might have created confusion.
