What does vagrant halt do in hyper v?

I currently use vagrant with virtual box on my Windows 10 box. I mostly love it BUT would like to see if I can improve performance on the VM side of things.

I've been thinking about wsl2, or maybe just running vagrant ON hyper v instead, but I'm a bit confused about how hyper v works.

For example, right now when I'm not coding I just run vagrant halt to suspend my VM and improve performance on my Windows box (when I no longer need the VM).

I've never used hyper v but I hear that it run parallel to the host and is "always on".

If that's the case, what does halt do? I thought a hyper v VMS couldn't be suspended? 🤔
