I just built a small home server (part list: https://pcpartpicker.com/list/7ZZZ9G).
I decided to use ZFS as my filesystem for data integrity reliability, the usual reasons. I have 2 pools, both mirrors, both with ashift=12: main which consists of the SSDs contains the OS and programs as well as any VMs I decide to create, and vault which consists of the 2 WD Reds, which holds my data.
Performance is horrible. I can’t get over 200MB/s on either pool in sequential reads and for encrypted datasets it’s even worse (55MB/s on both pools)! I’m testing with fio and caching disabled on the datasets. At these speeds, it won’t even keep up with a gigabit NIC. I have no idea what’s going wrong, I thought the SIMD issue was fixed with zfs-0.8.3. Anyone have any ideas? Thanks.
