I have a solr cluster of 7 shards, replicationFactor 2, running on 7 physical machines. Machine spec: cpu: 16 memory: 32gb storage is on local disks
Each machine runs 2 solr processes, each process with 6gb memory to jvm. The cluster currently has 330 million documents, each process around 30gb of data. Until recently performance was fine, but after a recent indexing which added arround 25 million docs, the search performance degraded dramatically. I'm now getting qtime of 30 second and sometimes even 60 seconds, for simple queries (fieldA:value AND fieldB:value + facets + highlighting) Any idea how can I check where the problem is? Could it be that the recent indexing caused the cluster to choke, and each its limit, and now I need to add more shards? (either split, or reindex to a new collection with more shards) Thanks. -- View this message in context: http://lucene.472066.n3.nabble.com/solr-qtime-suddenly-increased-in-production-env-tp4082605.html Sent from the Solr - User mailing list archive at Nabble.com.
