Hi Folks, The following patch adds an AVX implementation of the RAID5 xor checksumming functions. Based on xor_speed, the AVX implementation appears to be ~32% faster than the SSE implementation on my i7 2600: generic_sse: 15088.000 MB/sec avx: 19936.000 MB/sec Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
