I have 7 days of data in 3 node cluster. 1 shard per index with one segment. I am planning to have data for 90 days later. I try to view data for last 90 days(only 7 days of data really available) using date picker in kibana. i start with clearing the cache. Initial load take 70 seconds and then when i use the same time range took time goes to 4ms. when change the time range again first call take over 1 min and goes below 1 second when i do the same search again. How can I improve this? Other info: Es, kibana - 6.3.0 3 nodes with 4core 15gb with 7gb assigned to heap index size is 2.2gb and has one replica 9 visualizations in the dashboard ---

What kind of server/hardware is this deployed on? How many visualisations does your dashboard have? ---

So you have 14 shards in the cluster and only around 15GB of data? What is the output of the [cluster stats API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-stats.html)? Are you indexing at the same time you are querying? Do you have anything else running on these nodes? ---

I don't do any indexing at the moment. Nothing else is running on this cluster. Now I have 18 shards as I added 3 indexes in the mean time. cluster stats API Output > { > "\_nodes": { > "total": 3, > "successful": 3, > "failed": 0 > }, > "cluster\_name": "nuwans-elk-cluster1", > "timestamp": 1547537312699, > "status": "green", > "indices": { > "count": 24, > "shards": { > "total": 48, > "primaries": 24, > "replication": 1, > "index": { > "shards": { > "min": 2, > "max": 2, > "avg": 2 > }, > "primaries": { > "min": 1, > "max": 1, > "avg": 1 > }, > "replication": { > "min": 1, > "max": 1, > "avg": 1 > } > } > }, > "docs": { > "count": 490350031, > "deleted": 26139547 > }, > "store": { > "size": "43.7gb", > "size\_in\_bytes": 46980963876 > }, > "fielddata": { > "memory\_size": "57.7kb", > "memory\_size\_in\_bytes": 59104, > "evictions": 0 > }, > "query\_cache": { > "memory\_size": "0b", > "memory\_size\_in\_bytes": 0, > "total\_count": 0, > "hit\_count": 0, > "miss\_count": 0, > "cache\_size": 0, > "cache\_count": 0, > "evictions": 0 > }, > "completion": { > "size": "0b", > "size\_in\_bytes": 0 > }, > "segments": { > "count": 442, > "memory": "324.4mb", > "memory\_in\_bytes": 340159639, > "terms\_memory": "278.6mb", > "terms\_memory\_in\_bytes": 292200192, > "stored\_fields\_memory": "29.4mb", > "stored\_fields\_memory\_in\_bytes": 30931216, > "term\_vectors\_memory": "0b", > "term\_vectors\_memory\_in\_bytes": 0, > "norms\_memory": "4.8kb", > "norms\_memory\_in\_bytes": 4992, > "points\_memory": "14.2mb", > "points\_memory\_in\_bytes": 14893247, > "doc\_values\_memory": "2mb", > "doc\_values\_memory\_in\_bytes": 2129992, > "index\_writer\_memory": "0b", > "index\_writer\_memory\_in\_bytes": 0, > "version\_map\_memory": "0b", > "version\_map\_memory\_in\_bytes": 0, > "fixed\_bit\_set": "0b", > "fixed\_bit\_set\_memory\_in\_bytes": 0, > "max\_unsafe\_auto\_id\_timestamp": 1547510407937, > "file\_sizes": {} > } > }, > "nodes": { > "count": { > "total": 3, > "data": 3, > "coordinating\_only": 0, > "master": 3, > "ingest": 3 > }, > "versions": [ > "6.3.0" > ], > "os": { > "available\_processors": 12, > "allocated\_processors": 12, > "names": [ > { > "name": "Linux", > "count": 3 > } > ], > "mem": { > "total": "43.5gb", > "total\_in\_bytes": 46799904768, > "free": "1.1gb", > "free\_in\_bytes": 1190825984, > "used": "42.4gb", > "used\_in\_bytes": 45609078784, > "free\_percent": 3, > "used\_percent": 97 > } > }, > "process": { > "cpu": { > "percent": 17 > }, > "open\_file\_descriptors": { > "min": 344, > "max": 366, > "avg": 351 > } > }, > "jvm": { > "max\_uptime": "9d", > "max\_uptime\_in\_millis": 781731013, > "versions": [ > { > "version": "1.8.0\_191", > "vm\_name": "OpenJDK 64-Bit Server VM", > "vm\_version": "25.191-b12", > "vm\_vendor": "Oracle Corporation", > "count": 3 > } > ], > "mem": { > "heap\_used": "9.8gb", > "heap\_used\_in\_bytes": 10625182904, > "heap\_max": "20.9gb", > "heap\_max\_in\_bytes": 22443982848 > }, > "threads": 243 > }, > "fs": { > "total": "1.1tb", > "total\_in\_bytes": 1288439058432, > "free": "1.1tb", > "free\_in\_bytes": 1223634808832, > "available": "1.1tb", > "available\_in\_bytes": 1223634808832 > }, > "plugins": , > "network\_types": { > "transport\_types": { > "security4": 3 > }, > "http\_types": { > "security4": 3 > } > } > } > } ---
