I will preface this by saying I am really new to all of the unraid/zfs fun but am learning and hope this is a reasonable spot for this post. I've been testing unraid 6.12 RC on my backup server with a zpool consisting of 8x10TB SAS drives and I've been happy with the performance. I decided last night to take the leap on my main server and re-create the array with a similar 8x10TB drives in a raidz2 zpool. Now I'm transferring everything back over with rsync over ssh (maybe that's my main problem) and the speeds are not great. I get around 200MB/s with large files. Maybe I'm expecting too much but that is much slower than I expected. IPERF3 is 9.41Gb/s and I was really thinking I'd be near maxing that out. Any thoughts/tips? I haven't tried zfs send yet, but maybe that's a better option.
