I have a solr query that has a qtime of 30-40ms. The response time varies around 200ms.

  • Fetching 800 documents at a time
  • Returning 10 fields from the search query
  • solr version 6.6

Solr Qtime - ~30ms

Solr response time - ~200ms

Cache statistics

If you see cache statistics,

  • QueryresultCache hits is ~10%
  • DocumentCache hits is ~30%
  • FilterCache hits is ~82%

Is there any setting which I can change to reduce the "response time" in solrconfig.xml or jetty.xml?

Should I increase the cache sizes of documentCache/queryresultcache/filtercache further more?

Solrconfig.xml:

<filterCache class="solr.FastLRUCache"
             size="1024"
             initialSize="512"
             autowarmCount="0"/>

<queryResultCache class="solr.LRUCache"
                  size="0"
                  initialSize="1024"
                  autowarmCount="512"/>
<documentCache class="solr.LRUCache"
               size="1024"
               initialSize="512"
               autowarmCount="0"/>

Jetty.xml thread pool configuration:

<Set name="ThreadPool">

  <New class="org.mortbay.thread.QueuedThreadPool">
    <Set name="minThreads">10</Set>
    <Set name="maxThreads">10000</Set>
    <Set name="lowThreads">20</Set>
  </New>

  <!-- Optional Java 5 bounded threadpool with job queue 
  <New class="org.mortbay.thread.concurrent.ThreadPool">
    <Set name="corePoolSize">50</Set>
    <Set name="maximumPoolSize">50</Set>
  </New>
  -->
</Set>

  • What does "Solr response time" measure? – MatsLindh May 09 '18 at 11:56
  • We are using new-relic as a monitoring tool. Solr-response time is the time measured by new-relic(which includes searching/fetching the required fields and transfer back the data to the server). – user2163880 May 09 '18 at 12:48
