In 2012, I was working for a company that did all the development for its Windows clients on an ancient version of Visual Studio running in a Windows 2003 VM, and I discovered that the Windows 2003 running in a VM could transfer files over the network faster than Windows 7 running on bare metal. I feel like transferring files over the network has been horrible in Windows ever since. Transferring over USB was often horrible as well, but that seems somewhat better now.
