sorry, im newbie and i have one question.
i read in here https://www.elastic.co/guide/en/elasticsearch/guide/current/_scale_horizontally.html, it have :
- “Increasing the number_of_replicas to 2”, the blogs index now has
nine shards: three primaries and six replicas. This means that we can
scale out to a total of nine nodes, again with one shard per node.
This would allow us to triple search performance compared to our
original three-node cluster.
i tried index database about 7526 hits,5 shards with index ,2 replicas, 3 node in one cluster , and SearchResponse result have 1313 hits.
I realize time search with one node or 3 node is same( response.getTook().getNanos() ) ,search in 1 node faster than 2 node, search in 2 node faster than 3 node.
My question is : Why? How to get max performance like Guide elasticsearch?
My PC run ubuntu 13.10,memory 8G, Intel® Core™ i3-4130 CPU @ 3.40GHz × 4 and use SSD
Thanks for your help.
