Ismael Juma commented on KAFKA-3174:
------------------------------------
Jay, I think you meant https://bugs.openjdk.java.net/browse/JDK-7088419 as your
link is for PPC and Java 9.
We should probably select an implementation in a static block based on the JVM
version until we drop support for Java 7.
> Re-evaluate the CRC32 class performance.

> URL: https://issues.apache.org/jira/browse/KAFKA-3174
> Project: Kafka

> Affects Versions: 0.9.0.0
> Reporter: Jiangjie Qin
> Fix For: 0.9.0.1

>
> 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.
