July 2, 20242 yr reconstruct write is enabled nothing is accessing arryay (I think) I'm using krusader. transferring file size is > 3GB ALL HDD's SMART have no problem Edit: It's NOT about network. I don't know why it's so slow. My array contains both SMR and CMR disk but the speed should be at least 50MB/s (hopefully 100MB/s) . Any advice is welcome. unraid-diagnostics-20240702-1302.zip Edited July 2, 20242 yr by plenty_box
July 2, 20242 yr Community Expert Start by running a single stream iperf test in both directions to confirm the LAN is good.

This is diags in the middle of a large thanks in advance
July 3, 20242 yr Community Expert Diags done't show any array activity, try this instead: pv /mnt/pool_name/path_to_large_file > /mnt/disk19/file_name post the output from that, and you can then delete that file: rm /mnt/disk19/file_name

July 20, 20241 yr Author It's NOT about a network problem. The read speed of the HDD itself is nearly 200 mb/s https://docs.unraid.net/legacy/FAQ/check-harddrive-speed/ But when I actually try to copy the data on this HDD to the array, I only get about 20-30 mb/s. I'm not even sure if I can accurately call this a ZFS pool. I have one HDD formatted with ZFS on Unraid and just use it like a cache pool. When I copy data from, say, another PC to the Array through LAN, I get speeds of about 100mb/s with no problems.
