Benoit Delbosc created KAFKA-15402: -------------------------------------- Summary: Performance Regression after Upgrading to 3.5.0 Key: KAFKA-15402 URL: https://issues.apache.org/jira/browse/KAFKA-15402 Project: Kafka Issue Type: Bug Components: consumer, producer Affects Versions: 3.5.1, 3.5.0 Reporter: Benoit Delbosc
Hi, After upgrading to Kafka client version 3.5.0, we have observed a significant increase in the duration of our Java unit tests. These unit tests heavily rely on the Kafka Admin, Producer, and Consumer API. When using Kafka server version 3.4.1, the duration of the unit tests increased from 8 seconds (with Kafka client 3.4.1) to 18 seconds (with Kafka client 3.5.0). Similarly, when using Kafka server version 3.5.1, the duration of the unit tests increased from 16 seconds (with Kafka client 3.4.1) to 25 seconds (with Kafka client 3.5.0). The performance regression is observed when either the client or server is upgraded to version 3.5.0 (or 3.5.1). I have come across the issue KAFKA-15178, which could be the culprit. I will attempt to test the proposed patch. In the meantime, if you have any ideas that could help identify and address the regression, please let me know. -- This message was sent by Atlassian Jira (v8.20.10#820010)
