Hi, I've got a set up as follows:
- 13 cores - 2 servers - running Solr 4.0 Beta with numShards=1 and an embedded zookeeper. I'm trying to figure out why some complex queries are running so slowly in this setup versus quickly in a standalone mode. Given a query like: /select?q=(some complex query) It runs fast and gets faster (caches) when only running one server: 1. ?fl=*&q=(complex query)&wt=json&rows=24 (QTime 3) When, I issue the same query to the cluster and watch the logs, it looks like it's actually performing the query 3 times like so: 1. ?q=(complex query)&distrib=false&wt=javabin&rows=24&version=2&NOW=1347911018556&shard.url=(server1)|(server2)&fl=id,score&df=text&start=0&isShard=true&fsv=true (QTime 2) 2. ?ids=(ids from query 1)&distrib=false&wt=javabin&rows=24&version=2&df=text&fl=*&shard.url=(server1)|(server2)&NOW=1347911018556&start=0&q=(complex query)&isShard=true (QTime 4) 3. ?fl=*&q=(complex query)&wt=json&rows=24 (QTime 459) Why is it performing #3? It already has everything it needs in #2 and #3 seems to be really slow even when warmed and cached. As stated above, this query is fast when running on a single server that is warmed and cached. Since my query is complex, I could understand some slowness if I was attempting this across multiple shards, but since there's only one shard, shouldn't it just pick one server and query it? Thanks!
