------------------------------------
Summary: Optimize CPU bottleneck caused by metrics capture
Key: KAFKA-14423
URL: https://issues.apache.org/jira/browse/KAFKA-14423
Project: Kafka
Issue Type: Improvement
Components: network
Reporter: Divij Vaidya
Attachments: Screenshot 2022-11-28 at 12.11.23.png
I ran a produce-only workload on a plaintext single broker. One of the main
findings was that
kafka.network.Processor.updateRequestMetrics(kafka.network.RequestChannel$Response
method is expensive to the extent that 90% of the time taken by
Processor.processCompletedSends() is taken by this method.
The flamegraph is attached.
The objective of this ticket is to optimize the performance of metrics
collection here.
