Thank you for posting in Wired Ethernet Communities.
We appreciate the information provided, however, we'd like to request for additional details such as system configuration to show the configuration and driver loaded on your I210. You may use our System Support Utility to scan your system and attach the output file in this thread.

You've mentioned these two components are connected, does it mean they are connected without switch?
Sorry for the delay. I have messed with a lot of things since the last post and I cannot duplicate the "exact" behavior stated above. Although it still drops off to 85MB/s occasionally and I have no clue. And yes it is via an unmanaged GB switch with just the two computers running. There are other things attached but they are off during these test and most importantly - any of my transfers. At the time I posted above, it was via a direct connection as I was trying to figure out the loss in MB/s.
I am not very IT thus my experience is limited with LAN setups. I use the new server for backup purposes - huge hard drive images. Thus the loss of 15-20MB/s can be hours of difference. My next future step will be independent adapters like X540-T2s. Hard drive setups can handle the speed.
I attached the SSD files for both computers via a Onedrive link. Thanks again and don't waste too much time on me.
Hi RTitan, I've checked the SSU files and noticed you have some VMs running in your desktop, have you tried turning it off then do the file transfer from i210 to 82579V and check the performance?
I'd also suggest checking with your system manufacturer for updated NIC drivers. The latest generic driver version for I210 is 22.214.171.124.
You may also look into disabling the offloading features in server to match your settings in desktop.
Hope this helps.
