As I know, the CRC check can be an time taking operation for each data packets and in turn, can have impact on throughput performance. Generally, it is recommended to keep this CRC configuration disabled. But someone is cautious can enable it on a need basis by knowing the possible reduction on throughput number. Regards, Ajay
