we have 100 gb ram on each machine . 20 gb - for heap . index size of big collection is 130 gb . the new second collection has only few documents , only few MB .
When we disabled new cores , performance has improved . Both collection using same solr.config , so they have same filter configurations . But the second collection very small , only few documents , so cache can not consume a memory . -- View this message in context: http://lucene.472066.n3.nabble.com/Performance-degradation-with-two-collection-on-same-sole-instance-tp4236774p4237354.html Sent from the Solr - User mailing list archive at Nabble.com.
