Description
This test is a part of cost effective low-end clusters - product improvements.
http://showfast.sc.couchbase.com/#/timeline/Linux/cloud/lowend/idle
In this test, we do the following steps.
- launch aws ec2 instances
- set up cluster
- load data and create indexes
- sleep for 30 minutes
- measure CPU utilization of the bucket and individual component when the cluster is idle
We see higher CPU utilization reported by ns_server in 7.0.1/2. The issue is reproducible. I open this issue to investigate why CPU utilization is higher in 7.0.1/2 when the cluster is idle.
