I have a Hyper-V host and 2 VMs. My host can transfer data between a backup server and itself between 80 - 100 MB/s (yes, megabytes per second)
The two VMs can transfer no faster than 2 MB/s, and typically average 0.4 MB/s. There's got to be something configured incorrectly, but I wouldn't know where to begin. Suggestions?
