You know, I'm wondering exactly how people come to conclusions like 'I've been impressed with the VM subsystem' or 'I'm sorry, but VM is lame'. You can't have it both ways. What type of software are you running in the background? What are you trying to do? What is the response of the system? What is 'lame' or 'impressive' VM performance, keeping in mind that such a fundamental part of the OS is difficult to rate? Are you even at all sure you are having issues with the VM subsystem? Etcetera.
