Description

Dear All,

JDK9 introduces a new API java.util.zip.CRC32C. Our early data show CRC32C provides additional performance benefits over CRC32 checksum.

We are proposing to add CRC32C as one of the checksum types in addition to Adler32 and CRC32. Performance data and prototype code changes will be submitted here soon. At the meantime, please feel free to provide your feedback and comments.

Thanks,
Yingqi Lu
