Moe Posted May 20, 2023 Share Posted May 20, 2023 Go easy on me, I am not great at this stuff. But I've been doing a ton of reading and hopefully I am providing some good information in this post. I have three computers. My main PC (Win 10), my HTPC (Win 10) and my Unraid server. My network is setup like this. Cable modem, to mesh wifi, to switch. From that switch it runs to another switch and some stuff that I am not worried about for this problem. The devices connected to the first switch don't interact with Unraid. The second switch is connected to the Unraid server, the HTPC and my Main pc. It looks like this, just to make sure I am clear. The server does have a cache drive. I have a 4GB file that I use for all the below testing. When I move the file from the HTPC to SERVER I get speeds that I would expect ~100MB/s When I move the same file back from the SERVER to the HTPC speeds dip a bit, but still reasonable ~75MB/s When I move the file from the HTPC to MAIN I get reasonable speeds ~75MB/s When I move the file from MAIN to HTPC speeds dip a bit ~60MB/s When I move from MAIN to the SERVER is when things really go south ~3MB/s When I move from SERVER to MAIN speeds are a bit better but still pretty bad and they fluctuate a lot ~15MB/s I have run iperf tests.

Vr2Io Posted May 20, 2023 Share Posted May 20, 2023 (edited) Iperf indicate not network problem, what OS use in "main", ? Could also try NFS ? Edited May 20, 2023 by Vr2Io Quote Link to comment
Moe Posted May 20, 2023 Author Share Posted May 20, 2023 Both the HTPC and MAIN are running Windows 10. Quote Link to comment
Frank1940 Posted May 21, 2023 Share Posted May 21, 2023 Make sure that you have the latest driver for the NIC that is in MAIN. (A number of years ago, I had a speed transfer issue and, after many sessions of hair-pulling, I found out that the Windows driver for the NIC had a bug in it and updating the driver corrected the issue.)

Moe Posted May 22, 2023 Author Share Posted May 22, 2023 Yesterday I was at Target and they had a USB-C to Ethernet adapter so I figured I would give it a shot just to possibly rule out my motherboards Ethernet port. It helped a little, I was getting 20-25MB/s rates. This morning I plugged it back into my motherboard ethernet port as I was going to try the driver update that Frank suggested. Before doing anything though I did another speed test and things were looking pretty good at 60-70MB/s. I've been testing periodically throughout the day and the last one I did was from SERVER to MAIN and I was getting 100MB/s. No idea what fixed it, all I did was change from a motherboard to USB adapter and the changed back to motherboard and speeds got better. I am not going to complain though. Quote Link to comment

As I recall, this was why the process of solving my speed problem was so aggravating! I would change something and the speed would temporarily improve. If there is a new Windows driver from the Manufacturer (MB or NIC), I would being very seriously considering doing the upgrade. (I usually avoid the MS hardware upgrades or third party driver sites when looking at upgrades/updates. I really got burned about 25 years with a MS provided network card driver for a Dell OEM Board. The driver converted the board into a hardware/software brick. I had to do a complete restore of a disk image to recover from that fiasco!) Quote Link to comment
