It's spending 4-5 seconds warming up your query cache. If 4-5 seconds is too much, you could reduce the number of queries to auto-warm with on that cache.
Notice that the 4-5 seconds is spent only putting about 420 queries into the query cache. Your autowarm of 50000 for the query cache seems a bit high. If you need to reduce that autowarm time below 5 seconds, you may have to set that value in the hundreds, as opposed to tens of thousands. -Todd Feak -----Original Message----- From: oleg_gnatovskiy [mailto:oleg_gnatovs...@citysearch.com] Sent: Friday, December 12, 2008 10:08 AM To: solr-user@lucene.apache.org Subject: Re: Query Performance while updating teh index Here's what we have on one of the data slaves for the autowarming. -- Dec 12, 2008 8:46:02 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming searc...@3f32ca2b main from searc...@443ad545 main filterCache{lookups=351993,hits=347055,hitratio=0.98,inserts=8332,evicti ons=0,size=8245,warmupTime=215,cumulative_lookups=2837676,cumulative_hit s=2766551,cumulative_hitratio=0.97,cumulative_inserts=72050,cumulative_e victions=0} Dec 12, 2008 8:46:02 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming result for searc...@3f32ca2b main filterCache{lookups=0,hits=0,hitratio=0.00,inserts=1000,evictions=0,size =1000,warmupTime=317,cumulative_lookups=2837676,cumulative_hits=2766551, cumulative_hitratio=0.97,cumulative_inserts=72050,cumulative_evictions=0 } Dec 12, 2008 8:46:02 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming searc...@3f32ca2b main from searc...@443ad545 main queryResultCache{lookups=5309,hits=5223,hitratio=0.98,inserts=422,evicti ons=0,size=421,warmupTime=4628,cumulative_lookups=77802,cumulative_hits= 77216,cumulative_hitratio=0.99,cumulative_inserts=424,cumulative_evictio ns=0} -- Dec 12, 2008 8:46:07 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming result for searc...@3f32ca2b main queryResultCache{lookups=0,hits=0,hitratio=0.00,inserts=421,evictions=0, size=421,warmupTime=5536,cumulative_lookups=77804,cumulative_hits=77218, cumulative_hitratio=0.99,cumulative_inserts=424,cumulative_evictions=0} Dec 12, 2008 8:46:07 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming searc...@3f32ca2b main from searc...@443ad545 main documentCache{lookups=87216,hits=86686,hitratio=0.99,inserts=570,evictio ns=0,size=570,warmupTime=0,cumulative_lookups=1270773,cumulative_hits=12 68318,cumulative_hitratio=0.99,cumulative_inserts=2455,cumulative_evicti ons=0} Dec 12, 2008 8:46:07 AM org.apache.solr.search.SolrIndexSearcher warm INFO: autowarming result for searc...@3f32ca2b main documentCache{lookups=0,hits=0,hitratio=0.00,inserts=0,evictions=0,size= 0,warmupTime=0,cumulative_lookups=1270773,cumulative_hits=1268318,cumula tive_hitratio=0.99,cumulative_inserts=2455,cumulative_evictions=0} -- This is our current values after I've messed with them a few times trying to get better performance. <filterCache class="solr.LRUCache" size="30000" initialSize="15000" autowarmCount="1000"/> <queryResultCache class="solr.LRUCache" size="60000" initialSize="30000" autowarmCount="50000"/> <documentCache class="solr.LRUCache" size="200000" initialSize="125000" autowarmCount="0"/> -- View this message in context: http://www.nabble.com/Query-Performance-while-updating-the-index-tp20452 835p20980669.html Sent from the Solr - User mailing list archive at Nabble.com.
