Hi, Erick! >>Right, are you falling afoul of the recursive shard thing? That is, >>if you shards point back to itself. As far as I understand, your >>shards parameter in your request handler shouldn't point back >>to itself.... No, my request handler don't points itself cause default is false. But I tested today, using classic shards parameter. Here is results:

On production I create a RAMDisk (mount -t tmpfs -o size=xxxM tmpfs /mnt/tmpfs/) and put my shards onto it. The QTime/RTime was magnificent. But the problem is, I dont have much RAM for it( Can it be my huge index, terms or maybe it's to much queries per minute, or row count or I made something wrong in my configs? And, can you please watch drive speed on your indexes? Is it the same? -- View this message in context: http://lucene.472066.n3.nabble.com/Poor-performance-on-distributed-search-tp3590028p3594683.html Sent from the Solr - User mailing list archive at Nabble.com.
