Does it mean that (I hope I hope) each time a process is created, it is assigned the most available CPU? Or does it mean something like, once you login, you are assigned a CPU, all your processes use that same CPU, etc.? Is there a FAQ about the SMP capabilities of FreeBSD? Is SMP capability embedded in FreeBSD 2.1.0-R? Or is it a FreeBSD- Current thingie? Secondly, what is a 'Unified VM/buffer', as opposed to any other swapping scheme? I have seen several references to this as a feature of the OS. Thanks!
