Hi Leann,
Jeremy Kerr did some testing a while back and noted that the PowerPC smp flavor should run on non-smp hardware, but did acknowledge there could be a slight performance degradation. Jeremy, do you still have the data available?
I haven't done any testing myself, so don't have any quantitative data on the performance impact. This was just information from checking out the kernel source and having a chat with Ben H, the powerpc kernel maintainer.
The issue is that some SMP-specific components will be present on UP builds, mainly spinlocks. Of course, there'll be no lock contention, but the instructions are still present. ISTR the estimate was around 1-2% performance difference.
