January 24, 20197 yr As title suggests I have a LAN transfer speed issue I cannot diagnose and fix. I know it is related to this Windows machine though. It is not UnRaid, and it is not the network. This PC used to saturate my 1 Gbps link during writes to Unraid. Now it hovers around 50-60 MB/s. At this point other than reloading a fresh install of Windows I don't know what to do. My googlefu is at its end. Any suggestions super welcome Other PCs plugged into the same port will saturate the 1 Gbps link writing to UnRaid. 110-112 MB/s solid. (this PC used to also) Been wanting to create a port channel for this PC anyway since my UnRaid server has a 4 Gbps channel-group So now this PC has 5 brand new CAT6 cables creating a 5 Gbps channel-group to my Cisco 3750X switch. Then the UnRaid server has a 4 Gbps channel-group also to the 3750X. The PC is no slouch. Windows 10 Pro, 64 bit. i7 5820k 6 core / 12 thread CPU, 32 GB DDR4. I've reloaded drivers, I've now added an additional NIC. Other than doing a fresh install of Windows I'm at the end of my rope. I don't know what to do. Any suggestions? Thanks, Andrew
January 24, 20197 yr Author SOB It was my firewall. I could SWEAR I had tried turning it off in the past to troubleshoot this issue. I turned off "Intrusion Detection Systems" and now I'm back to 112 MB/s. Would have thought I would be closer to my drive speed now that I have a 5gbps link but oh well. Im happy for now

Would have thought I would be closer to my drive speed now that I have a 5gbps link Pretty sure SMB transfers aren't multi channel, so to saturate the link you would need multiple diverse connections. I bet if you opened a FTP transfer and NFS at the same time you could get decent rates on all of them simultaneously.

Basically I created a multi-lane highway but did not increase the speed for one car LOLSent from my SM-G965U using Tapatalk
