Hi, I am using 2 fairly high powered physical machines as ES nodes, each has 96GB of memory and 1TB of RAID10 SSD. The Elasticsearch database is currently around 300GB with 450,000,000 documents. I am trying to understand which of these configurations would be optimal? 1. 1 x ES instance on each machine with 30GB Heap (for pointer compression reasons) 2. 1 x ES instance on each machine with 57.6GB (60% of total memory) Heap 3. 2 x ES instances on each machine, 30GB Heap for each -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, I think the 2nd proposition could be the worst. With more than 32GB the JVM will use uncompressed pointer. Take a look at this : [http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/\_limiting\_memory\_usage.html](http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_limiting_memory_usage.html) Hope this help -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I'd go with option 3 and use puppet to manage it.
