I used to emulate Mac on my Amiga and I learned that emulating can be useful. And I used a VMware Workstation 3.0 trial - and I suppose ESX/GSX servers are optimized for speed and workstation is optimized for desktop performance (after installing vmware_drv.o my XFree4 was almost as fast as on i810.o :). I suppose context switching is the bottleneck with AOLserver, even with threads... When I tried using tcllib's MIME for 15MB mail parsing, the VM Linux was actually faster (!) than real Win2000. About 5% faster. This was a nice thing to see. The PITA for emulating is the hardware required to emulate - like VGA graphics, soundcards and so on.
