It's not necessarily "so good" especially for workstation loads vs server loads. You have the same issue in Linux with the different config options (a simple example that's not relevant anymore: an smp kernel is slower than a single core one)

Yes, it could be a config option as well instead of a fixed choice.

The main reason this example is not relevant anymore is the "alternatives" system Linux uses nowadays, which dynamically patches the kernel code according to the hardware features (in this case, it detects it's running on a single core and removes the SMP locking code).

I remember reading in Inside Windows 2000 by Mark Russinovich & David Solomon that the non-SMP kernel was the exact same binary built from the exact same SMP-compliant code with all the SMP stuff NOP-ed out.
