-----------------------------------
Summary: Re-evaluate the CRC32 class performance.
Key: KAFKA-3174
URL: https://issues.apache.org/jira/browse/KAFKA-3174
Project: Kafka
Issue Type: Improvement
Reporter: Jiangjie Qin
We org.apache.kafka.common.utils.CRC32 because it has better performance than
java.util.zip.CRC32 in Java 1.6.
In a recent test I ran it looks in Java 1.8 the CRC32 class is 2x as fast as
the Crc32 class we are using now. We may want to re-evaluate the performance of
Crc32 class and see it makes sense to simply use java CRC32 instead.
