High CPU Usage Problem

Elastic Stack Elasticsearch
1

Hi everyone,

We indexed nearly 1.500.000 documents from our DB to elasticsearch and we're using it via one shard and 0 replica.

We have nearly 4000 request per second to elasticsearch, and CPU usage is minimum %90. We think, it's really high CPU usage for us.

Is this usage normal or do you suggest another way to make CPU usage low.

Thnx.
