Lucene Index taking a lot to time

[Birendar Singh Waldiya -X (bwaldiya - TCS at Cisco)]

Hi Gurus, 
 
We are using Lucene for creating indexes on some database column  and
suddenly my indexcreation time sems to have increased considerably, 
 
Here is the code snippet we are using ,  we are wondering how come the
index creation has increaed suddenly..any pointer please 
 
Date start = new Date();
   Map inputParams = new HashMap();
         IndexWriter writer = new
IndexWriter(SDSUtil.getSDLuceneIndexDirectory(), new
StandardAnalyzer(),true, IndexWriter.MaxFieldLength.UNLIMITED);
   //IndexWriter writer = new
IndexWriter(SDSUtil.getSDLuceneIndexDirectory(), new
StandardAnalyzer());
   logger.info("Adding records - Before creating Lucene Index");
   CreateLuceneIndexPr createLuceneIndexPr = new
CreateLuceneIndexPr(sdsJdbcTemplate, writer);
   Map outParams = createLuceneIndexPr.execute(inputParams);
   
   //now add partner Exceptions also to index
   List ptnrExcpnList = getPartnerExceptionList("vipmistr"); //TODO:
change it:passing userId as blank to get all prtnr Excpns
   
  for (Iterator iter = ptnrExcpnList.iterator(); iter.hasNext();) {
    PartnerException partnerException = (PartnerException) iter.next();
    Document doc = new Document();
    doc.add(new Field("intd_id", "",
org.apache.lucene.document.Field.Store.NO,
org.apache.lucene.document.Field.Index.NOT_ANALYZED));
             doc.add(new Field("cntry_id", "",
org.apache.lucene.document.Field.Store.NO,
org.apache.lucene.document.Field.Index.NOT_ANALYZED));
             doc.add(new Field("Technology_Node", "",
org.apache.lucene.document.Field.Store.YES,
org.apache.lucene.document.Field.Index.NO));
             doc.add(new Field("product_id", "",
org.apache.lucene.document.Field.Store.NO,
org.apache.lucene.document.Field.Index.NOT_ANALYZED));
             doc.add(new Field("RULE_AUT_SPEC", "",
org.apache.lucene.document.Field.Store.YES,
org.apache.lucene.document.Field.Index.NO));
             doc.add(new Field("ptnrExcpn",
partnerException.getPgtmvBeId(),
org.apache.lucene.document.Field.Store.YES,
org.apache.lucene.document.Field.Index.NOT_ANALYZED));
             writer.addDocument(doc);
   }
   logger.info("Optimizing...");
   writer.optimize();
   writer.close();
   Date end = new Date();
   logger.info("#################Index Create Time :-->>>>> " +
(end.getTime() - start.getTime()) + " milliseconds");
  } catch (Exception e) {
   if (e instanceof DAOException) {
    throw (DAOException) e;
   } else {
    e.printStackTrace();
    throw new DAOSystemException("error.admin.error",e);
   }
  }
 }
