Were any changes made to MDAG in Windows 11? Or is it the exact same as in Windows 10?

Hello, and welcome. :alien:

It's the same.
Hello and thank you!

That's a bit disappointing. I was hoping for better performance. Hyper-V is currently nowhere near the speeds of Xen for example.

Maybe in Windows 12.

I find that having the VM's saved to a M.2 NVMe SSD helps make them run faster. In addition, be sure to also assign enough RAM (at least 4GB) for the VM.

Yeah I actually do use a M2 SSD with quite a bit of RAM, but unfortunately MDAG, Windows Sandbox or literally any other native virtual machine on Windows 10 just isn't close to the near-native speeds of KVM or Xen.

Maybe it's my CPU. It's apparently 7 years old at the moment. I've just never noticed its age before with literally anything else. Oh well.
