Re:Re: solr search speed is so slow.

[Rong Kang]

Thanks for your reply.

I didn't use any other params except  q(for example 
http://localhost:8080/solr/search?q=drugs). no facet, no sort.
I don't think configure newSearcher or firstSearcher can help, because I want 
every query can be very fast. Do you have other solution?
 I think 460ms is too slow even though a word  is firstly searched.


My computer 's setting:
cpu: amd 5000, 2.2GHz, 1 cpu with 2 cores.
main memory: 2G, 800Mhz
disk drive : 7200r/min
 
This is my  full search configuration:


  <requestHandler name="/search" 
class="org.apache.solr.handler.component.SearchHandler">
       <lst name="defaults">
          <str name="wt">xslt</str>

          <int name="maxAnalyzedChars">-1</int>
          <str name="echoParams">all</str>
          <str name="indent">off</str>
           <str name="fl">filename</str>
          <int name="rows">10</int>
          <str name="defType">dismax</str>
