I've been trying VMWare Fusion for a few weeks now, and am trying to decide whether to buy. It frequently bogs down my Mac even when just sitting on the XP desktop with no apps running. Is this normal? Solvable? * 2.33 Ghz iMac Core 2 Duo / nVidia 7600 * 2 GB RAM, 80 GB free HD space * Latest versions of VMware and Tiger, set to use one processor and 640 MB RAM * Activity Monitor shows plenty of unused CPU cycles * About 25-75 MB free RAM, 575 MB inactive. Very little network or disk activity. And yet I find that windows and menus open slowly, typing is delayed, Dock responds slowly--everything, pretty much. Not all the time, and sometimes worse than others, but it definitely only happens when I have VMWare running. These little delays really feel as though I have a very slow HD. (The Windows side doesn't seem all that fast either.) Any thoughts? Is this just what you have to live with running two OS's at once? Is Parallels better? I compare it to running XP in VPC on my single G4 with 1 GB RAM: Windows may be slow, but it doesn't slow down the Mac.
