ZFS SMI vs EFI performance using filebench
...performed better than any striping configuration I came up with. We don''t use any software RAID of any kind.. because the SAN does it all for us. One interesting test revealed better performance using the SMI label on our LUNs than that EFI label. This is true for using the fileserver, large_db_oltp_8k_uncached, and large_db_oltp_8k_cached workloads from filebench. The fileserver differences were not that great, but he db workloads performed 4x better using the SMI labeled LUNs as opposed to the EFI labeled LUNs. Does anyone know why ZFS would perform better with the SMI labeled luns that the EFI labele...
