Hi, we currently have 2 servers running on JBoss container (master and slave) with 20mln documents and about 3GB index size. Java was executed with options: *-Xms12G -Xmx12G -XX:NewSize=4G -XX:MaxNewSize=4G -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -XX:+UseCompressedOops -XX:+UseTLAB -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled*
Commit duration on master is 5 minutes and we use Solr 3.3 (because in 3.4 we have a problem with dataimport https://issues.apache.org/jira/browse/SOLR-2804). We have problem that occurs when server gets about *34* qps. *Do you have any advice how to fix this problem?* I have attached the charts below. The load and threads count increases between 19:00 and 20:00. On 20:10 we reduced by half the number of queries. http://lucene.472066.n3.nabble.com/file/n3527914/solr_users_reqs-day.png http://lucene.472066.n3.nabble.com/file/n3527914/load-day.png http://lucene.472066.n3.nabble.com/file/n3527914/threads-day.png http://lucene.472066.n3.nabble.com/file/n3527914/jboss_threads-day.png http://lucene.472066.n3.nabble.com/file/n3527914/cpu-day.png http://lucene.472066.n3.nabble.com/file/n3527914/_avg_response_query_time-22-11-2011_15_50_17.png -- View this message in context: http://lucene.472066.n3.nabble.com/Unexpected-cpu-load-and-Solr-incrase-response-time-tp3527914p3527914.html Sent from the Solr - User mailing list archive at Nabble.com.
