Jiangjie Qin commented on KAFKA-3174:
-------------------------------------
Thanks for the info [~gwenshap]. We have also been using Java 1.8 for a while
and did not see any issue as far as I know. [~toddpalino] can comment. Should
we start to recommend people to use Java 1.8 while still supporting 1.7? We can
put a note warning people about the potential CRC performance degrade if they
are using 1.7.
> Re-evaluate the CRC32 class performance.

> 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.
