Good morning, I'm having issues with transfer speeds from windows pc to unraid share. I've been reading the forum for the past week and haven't been able to solve my problem, tried direct IO on, jumbo packets, turbo write enabled and don't know what else.
when I copy a large document from windows to unraid it peaks at about 1100 MB/s and then drops to under 100 MB/s
iperf3 performs just fine:
