Subject Re: Lucene 3.0 Search Performance Stats
Date Fri, 19 Mar 2010 17:04:05 GMT
Hi Jamie,

  could you please tell us how much memory does your application consume
with Lucene? I'm asking it because we are having memory consumption problems
with a 32GB index and 1.5GB od RAM allocated to our web application. At the
momento, we use textual search.
 Thanks in advance,
Monique
