We are using couchbase DB with our products and we tested it under heavy load. The Database is performing well within first half an hour, after that performance is reduced.
Server (environment) details as follows,
- OS : CentOS 6.7
- RAM: 16GB
- Disk : 80 Gb
Data Bucket details,
- RAM : 7GB
- Data RAM Quota : 8 GB
- Index RAM Quota : 4 GB
- SDK version : 2.2.6.RELEASE
- Server Version: couchbase-server-enterprise-4.6.2-centos6.x86_64
Databse server has only one node.
We applied OS level changes to the couchbase server node based on below article, still we were unable to get consistent performance.
Please guide us to identify the possible bottlenecks and get the database server into optimum performance.
