January 19, 20197 yr Community Expert Are you sure it is writing to cache? Maybe you have filled cache and it is overflowing to the parity array. Maybe other things I could speculate without diagnostics.
January 19, 20197 yr Community Expert Enable turbo write and transfer directly to the array, if speeds are the same problem is likely not the Unraid server, but source or network.

January 20, 20197 yr Community Expert It's been a while since I used N40L's with Unraid, they do have a slow CPU, but it was enough for basic NAS functyions ehrn I had them, it could be the newer kernels require a little more CPU power but I suspect it's the encryption: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2 0.0 0.0 0 0 ? S 17:40 0:00 [kthreadd] root 9903 8.7 0.0 0 0 ? I< 17:41 4:54 \_ [kworker/u9:0-kcryptd] root 9908 8.4 0.0 0 0 ? I< 17:41 4:44 \_ [kworker/u9:2-kcryptd] root 9790 2.8 0.0 0 0 ? S 17:41 1:37 \_ [unraidd] If this is idle, it's a non negligible amount of CPU time.
