I made a post a couple days ago that I Was helped with and moved all of my vms over to hyperv. I rebuilt all of my vms and this includes my steam cache, I got my cache up and running and when I check the logs it looks like I am only getting half the game saved on the hard drive at most.
I have no idea why it's not saving as the test game I was using is 5gb and the cache size is 1860gb. I don't know if I need to follow a new guide or go elsewhere to set up my cache. The speed is doing fine, it's around 70mbs for the first 500mb or so then that is all my cache caches.
