July 19, 2025Jul 19 I'm running a script on my Windows VM that is reading a file from the Array, processing it, writing an intermediate file to the virtual C: drive (which Unraid VM reports as "/mnt/user/domains/Windows 11/vdisk1.Windows--generateqcow2 (cache) vdisk1 SATA"). Then it does further processing on the temp file and writes the result back to the Unraid Array. The files on the Unraid array are access with UNC paths. \\unraid\share\and\some\path\and\file.datAs I monitor performance in the Windows environment it seems to be network limited. The system is showing network throughtput flatlining at 1 Gigabit per second. The data is to the host IP of the parent Unraid instance. CPU is about 30%.When I look at the network interface in the Windows VM, it is called "Ethernet Instance 0", and it reports a speed of 10 Gbps. Why would the access to the Array in the VM's parent Unraid instance be limited to 1 Gbps? It is not passing over a physical Ethernet at all.
