We have a cluster of three nodes with same hardwares. We have made some http benchmark test on: - one index of 4 million docs, 5 shards, 1 replica - use golang client `gopkg.in/olivere/elastic.v6` connect to all three nodes. The coordinate node should not be focused on one node - es version: 6.5.4 - this is a pure benchmark test environment, no other application processes and no other es query / index requests ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/4/f4021ef1fbafb40e6d741da4d932b5df8f41fb24.png) ---

Does your data distribute evenly across three nodes? ---

The shards distribution seems to be evenly. ```auto index shard prirep state docs store node quick_match_v1 3 p STARTED 847408 570.7mb matchtest_es-node-172.16.0.223 quick_match_v1 3 r STARTED 847408 570.7mb matchtest_es-node-172.16.0.222 quick_match_v1 2 r STARTED 847348 559.9mb matchtest_es-node-172.16.0.223 quick_match_v1 2 p STARTED 847348 559.9mb matchtest_es-node-172.16.0.221 quick_match_v1 4 p STARTED 846896 568.2mb matchtest_es-node-172.16.0.222 quick_match_v1 4 r STARTED 846896 546.8mb matchtest_es-node-172.16.0.221 quick_match_v1 1 p STARTED 845880 587.8mb matchtest_es-node-172.16.0.223 quick_match_v1 1 r STARTED 845880 575.7mb matchtest_es-node-172.16.0.221 quick_match_v1 0 r STARTED 848310 570.9mb matchtest_es-node-172.16.0.223 quick_match_v1 0 p STARTED 848310 570.9mb matchtest_es-node-172.16.0.222 ``` ---
