October 5, 20241 yr Just a post for anyone investigating poor network performance, I didn't see this in the VM FAQ. It is imperative to isolate the cores for the VM along side pinning. Make sure you have enough cores for the speed you are looking for, pin and isolate. I had cores pinned but could not figure out why the performance was so bad, I was getting around 1.3gbps to Unraid, and to another VM on the same network. After isolating the cores I pinned, I am now getting full line speed (40gbps) to Unraid, and other VMs on the same VLAN. This is just an FYI since I did a lot of searching and didn't see anyone talking about the need for isolating as well as pinning.
