Hrm, linux uses "extra" memory for stuff like page cache... I assumed W2K did the same, which would mean that W2K using "extra" memory for its own cache would require VMWare to malloc that much for the guest, or keep some on (hopefully fast) disk. Guess not.

How much is the si/so "activity"... < 10? < 20? < 50? Yes, some bi and bo activity is expected, but was the bi and bo unusually high during that period? Or CPU?

Part of sysstat, like sar. Shows things like blocks read/written, and read/written per second, for block devices.
Other than that I'm afraid I don't know enough about VMWare to help you beyond what I have. Have you checked out vmware performance tips? A quick search pulled up these two items:

HTH and good luck!
