Hi all Currently in my cluster, i have 3 data node in total, the query performance is fine but i really wanted it to be better, so other than doing all the thing that some blog say i should on the internet, i was just wondering if i increase the number of data node, will the searching performance be better since it has more cpu and ram. Thank you for your time ---

How large is your data set? Are you looking to improve latency and/or query throughput? What is the specification of the hardware currently used? ---

well most of them are about 300GB and some are more, i config them to have 3 or 6 shards for each indices and all of them has 1 replica shards ---
