Hi, Our index is divided into two shards and each of them has 120M docs , total size 75G in each core. The server is a pretty good one , jvm is given memory of 70G and about same is left for OS (SLES 11) .
We use all dynamic fields except th eunique id and are using long queries but almost all of them are filter queires, Each query may have 10 -30 fq parameters. When I tested the index ( same size) but with max heap size 40 G, queries were blazing fast. I used solrmeter to load test and it was happily serving 12000 queries or more per min with avg 65 ms qtime.We had an excellent filtercache hit ratio. This index is only used for searching and being replicated every 7 sec from the master. But now in production server it is horribly slow and taking 5 mins(qtime) to return a query ( same query). What could go wrong? Really appreciate your suggestions on debugging this thing.. -- View this message in context: http://lucene.472066.n3.nabble.com/Using-Solr-3-4-running-on-tomcat7-very-slow-search-tp3995436.html Sent from the Solr - User mailing list archive at Nabble.com.
