> h2. 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.
> h2. What needs to be done
> * Create a microbenchmark
