Installed macOS Big Sur and upgraded to Fusion Pro 12. I have a powerful mac w 8TB and gobs of RAM. My internet is pathetically slow in my windows 10 VM. 6 Mbps download and 20 up in the vm. On the host MacOS it is 400 down. I have tried changing my network Adapter from Wi-Fi to Share with Mac, tired private connection, and there was no difference. Even tried to hard wire the internet connection and that managed to get it up to 70 mbps. I have a 4 TB image and 8 processors in the settings. Any advice? I have also been getting bluescreens in the VM. 

Is there a way to downsize the image? I can only seem to increase it in the settings. I am wondering if it is too big?
