Sure it does decrease performance on UP systems. It's just a question whether the loss does justify shipping an extra kernel. But to decide this you should do benchmarks about how much performance is lost. On hyper-thread processors it is even a question whether the performance loss by using an SMP kernel outweighs the speed gain by activating hyper-threading. Actually I don't know the answer about this question because I never meassured it and it is most likely dependant of your system usage pattern.
