We want to use elastic for a system with large amount of data. now we index **60k/s** data in our single node elasticsearch. I want to understand what is the max performance we can reach in single node. and which parameters I should check to find resource bottlenecks. after we reach max performacne in single node, we decide to scale out our cluster. **so how can I investigate parameters for increase performance and find bottlnecks?** - elasticsearch version : 5.6 - java api with bulk load and 10 threads - 1 index in elasticsearch with 5 shard and 0 replicas - swapping is disable - custom mapping (disable \_all , some filed has index:false) - heap is 32 GB - total Memory : 64 GB - 32 cores cpu ---
