I remember reading the VPC for OS X beta discussions a while back and seeing that Connectix went so far as to run an informal poll. They were pretty sure at the time that they would not be able to get the same kind of performance out of VPC under OS X that they were able to achieve under OS 9. That's not surprising given the memory model and other changes that they would have to work around (if they were able to get around them at all). Does anyone know if these hurdles were overcome? I notice that performance is NOT something that Connectix talks about in the VPC 5.0 press release.
