we have a large solr cloud , with one collection and no replicas . Each machine has one solr core . Recently we decided to add a new collection , based on same schema , so now each solr instance has two cores . First collection has very big index , but the new one has only several hundreds of documents.
Day after we did it , we experienced very strong performance degradation, like long query times and server unavailability. JVM was configured to 20GB heap , and we did not changed it during addition of a new collection. The question is , how Solr manages its resources when it has more than one core ? Does it need twice memory ? Or this degradation might be a coincidence ? -- View this message in context: http://lucene.472066.n3.nabble.com/Performance-degradation-with-two-collection-on-same-sole-instance-tp4236774.html Sent from the Solr - User mailing list archive at Nabble.com.
