title: Speeding up SOLR search
body: <p>The SOLR search response is extremely slow using SOLR Apache Lucene 3.6. </p>
  
  <p>Some performance enhancement techniques I'm experimenting with are </p>
  
  <ul>
  <li><p>SOLR Pagination</p></li>
  <li><p>mergeFactor currently set to 10 in solrConfig.xml</p></li>
  <li><p>SOLR Facet queries</p></li>
  <li><p>filterCache in solrconfig.xml set to size 512 and using
  solr.FastLRUCache and  autowarm = 0;</p></li>
  <li><p>queryResultCache in solfconfig.xml set to size 512 with
  autowarmCount=0</p></li>
  <li><p>newSearcher, firstSearcher, and useColdSearcher</p></li>
  <li><p>single segment index for 100,000 documents</p></li>
  <li><p>single machine SOLR server for 100,000 documents</p></li>
  </ul>
  
  <p>How can I optimize items 1-7 to increase SOLR search response for a term/query?
  Are there any other optimization parameters to consider not mentioned above?</p>
