    Description

      Overview

      As a part CASSANDRA-16360 there was a need to change the checksum algo from CRC32 to CRC32C for client/internode messaging. Before making that change it would be nice to have a way to measure performance for checksum calculation (similarly to HashingBench for hash calculation).

      In fact, the microbenchmark has been already created as a part of that ticket. However, after running it I saw a performance degradation for Java 8. After a discussion among the community, it was decided to wait with CRC32C until Java 8 support is abandoned. The purpose of this ticket is to merge the benchmark changes separately.

      What needs to be done

      • Create a microbenchmark
