I have an 8 year old desktop PC, Gigabyte mobo, Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz, 16 GB RAM, 3x8TB HDs, 3x3TB HDs, Gigabit net port. I've uploaded the hardware spec for further information. During a parity check it can take up to 24 hours, and the fastest write speeds I see are 150MB/s, which seems awful slow. Also when writing to the UNRAID over NFS from a Ubuntu 22.04 server the rsync starts at 200-300 MB/s but then slows down to 3.7 MB/sec and slower. Can anyone give me some suggestions on how to get more performance.
Thanks.
