I haven't seen any performance numbers talking about how well this
stuff works on single or dual CPU machines with smaller amounts of
memory, or whether it's worth using on these machines at all?

The big machines with lots of memory and lots of CPUs are certainly
becoming more prevalent, but for my home machine with 4Gb RAM and dual
core, what's the advantage?  

Let's not slow down the common case for the sake of the bigger guys if
possible.
