I've looked through documentation and postings and expect that a single filter cache entry should be approx MaxDoc/8 bytes.
Our frequently updated index (replication every 3 minutes) has maxdoc ~= 23 Million. So I'm figuring 3MB per entry. With CacheSize=512 I expect something like 1.5GB of RAM, but with the server in steady state after 1/2 hour, it is 7GB larger than without the cache. I can understand maybe a 2x difference, given the warming searcher but 4x I don't understand. I do have maxWarmingSearchers = 2, but have never seen 2 searchers sumiltaneously being warmed. Ideas anybody? -- View this message in context: http://lucene.472066.n3.nabble.com/FilterCache-Memory-consumption-high-tp4008444.html Sent from the Solr - User mailing list archive at Nabble.com.
