Currently I am running 2gb of ram on a unibody Macbook Pro. I've been disappointed with VMware 2.0 so far. It's pretty sluggish for trying to do anything even just basic office documents. I don't know what the limited factor is in the system though. When I run Vista with 768mb of ram assigned to it, the task manager shows less than 500mb being used with just microsoft office open. My copy of Vista is freshly installed and I don't have any extra processes going on. The total number of processes in Vista is 51. If I have 768mb of ram assigned to Vista and it's only using 500 I'm assuming that ram isn't my limiting factor but I'm not sure. I'm wondering if maybe it's the hard drive since it's being accesses by two different operating systems? Anyways, will increasing my ram to 4gb solve this issue?
