    Description

      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.
