I was searching for ES performance by google and I find some documents. They says modify ES config is good for ES performance. So, I edit my ES config like below. _/etc/elasticsearch/elasticsearch.yml_ index.number\_of\_replica: 0 index.number\_of\_shards: 3 index.translog.flush\_threshold\_ops: 50000 index.refresh\_interval: -1 indices.memory.index\_buffer\_size: 50% index.store.type: mmapfs bootstrap.mlockall: true _/etc/default/elasticsearch_ ES\_HEAP\_SIZE: 4g (my machine has 8g RAM) MAX\_LOCKED\_MEMORY=unlimited After configure above restart ES and LS. _# /etc/init.d/elasticsearch restart && sudo restart logstash_ And make sure ES setting is correctly using curl command. _# curl 'localhost:9200/logstash-iis-test04/\_settings?pretty'_ { "logstash-iis-test04" : { "settings" : { "index" : { "creation\_date" : "1426555104697", "uuid" : "0PuOIGj-RnKS9cMKXbsryQ", "number\_of\_replicas" : "0", "number\_of\_shards" : "3", "refresh\_interval" : "5s", "version" : { "created" : "1010199" } } } } } ​As you see, index.number\_of\_replicas and index.number\_of\_shards values is correct but , index.refresh\_interval is not correct (I set this value is -1) and another setting is not shown, where can I find another settings? I want to see settings like index.translog.flush\_threshold\_ops, index.refresh\_interval, indices.memory.index\_buffer\_size, index.store.type, bootstrap.mlockall.. and want to know this settings is correctly applied. Maybe you know why this result is shown, please advice to me. Regards -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

​Take a look at > **[Cluster APIs | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster.html)** for other settings.
