Now, with all my whining and complaining aside, the IOMMU code in tiger has gotten *much* better. With tiger, pinning memory is nearly as fast as it is on a DAC machine. However, the address space is still limited. There's nothing they can do about that.

You don't have to constantly pin/unpin memory if your OS is sophisticated enough to be able to manage the process better. While Tiger can't currently do this, Solaris for one can. Though given today's Intel announcement, our discussion is largely moot at this point, as the entire Mac universe, and its performance characteristics, is about to change drastically.
