Ismael Juma commented on KAFKA-3174:
------------------------------------
[~toddpalino], let us know when you switch to u40 so that we update the docs to
say that (particularly important if you are getting SEGVs with Mirror Maker!).
> Re-evaluate the CRC32 class performance.

> Key: KAFKA-3174
> URL: https://issues.apache.org/jira/browse/KAFKA-3174
> Project: Kafka
> Issue Type: Improvement
> Affects Versions: 0.9.0.0
> Reporter: Jiangjie Qin
> Assignee: Jiangjie Qin
> Fix For: 0.9.0.1
>
>
> We used org.apache.kafka.common.utils.CRC32 in clients 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.
