--- Comment #1 from Ben RUBSON <ben.rub...@gmail.com> --- Some benchmarks with this : https://github.com/laanwj/crcbench On an Intel E5-2620v3 : # ./crcbench CRC32C benchmarks [sw] 65543000 bytes in 69730us monotonic 69726us CPU (940.0MB/s) [hw-sse42] 65543000 bytes in 12619us monotonic 12618us CPU (5194.4MB/s) On more data (10GB) : # ./crcbench CRC32C benchmarks [sw] 10485767000 bytes in 11179263us monotonic 11178667us CPU (938.0MB/s) [hw-sse42] 10485767000 bytes in 2028412us monotonic 2028305us CPU (5169.7MB/s) Sounds really interesting and promising. Enabling HeaderDigest and DataDigest makes my iSCSI throughput drop from 300MB/s to 200MB/s. Hardware CRC32C should help minimising this difference. Thank you !
