>                 Key: MINIFICPP-246
>                 URL: https://issues.apache.org/jira/browse/MINIFICPP-246
>             Project: Apache NiFi MiNiFi C++
>          Issue Type: Improvement
>            Reporter: Bryan Rosander
>            Priority: Minor
>
> Currently in Site-to-Site heavy flows, MiNiFi C++ spends a considerable amount of time calculating CRC32 checksums.
> We should investigate whether CRC32C provides a noticeable performance bump.
> If we get a big speedup by switching from CRC32 to CRC32C (on Intel at least it's supposed to be a lot faster) we should consider adding support to the NiFi s2s implementation for CRC32C and then after NiFi release we could move in that direction for MiNiFi.
