Summary: CPU increase after the upgrade to Kafka 2.5 Key: KAFKA-10649 URL: https://issues.apache.org/jira/browse/KAFKA-10649 Project: Kafka Issue Type: Bug Components: core Affects Versions: 2.5.1 Environment: Ubuntu 16.04 Reporter: Valentina Glagoleva Attachments: CPU_usage_grafana.png After upgrade from Kafka 2.2.1 to Kafka 2.5.1 we noticed, that some of our clusters now use 10-15% more CPU than before: !CPU_usage_grafana.png|width=613,height=210! The increase happened right after the rolling upgrade of the cluster and CPU usage stayed higher than usual since then. We made no changes to the application side or usage patterns. What can be the reason for a CPU usage increase? -- This message was sent by Atlassian Jira (v8.3.4#803005)
