I am using daily indices, and they each have 3 shards, and 2 replicas. I chose these numbers because I have 3 physical servers, with 3 data nodes on each of them. The data nodes each have 2x 1TB disks in RAID0, 40GB of RAM, and 20GB is heap for Elasticsearch. The memory is locked, like most tutorials say. :slight_smile:
My monitoring instance also tells me that the load on data nodes never exceeds 10%!
