I run several Windows Virtual Machines (VMs) on my Mac with VMware Fusion. Even VMware Fusion has a great performance for Virtual Machines I am really happy about every performance increase I can get. I made a list with some tuning tips. Here is how you are tuning a Windows 7 VM.
- First use Windows Classic Theme
- Deactivate System Protection (You also win some Diskspace)
- Under System Properties –> Advanced –> Performance –> Choose Adjust for best Performance
- Deactivate Autostart objects with MSCONFIG
There are a lot of more tips out there but I think these are pretty important.
