Slowdown in SMP.

Correlates with slowdown in UP

Speedup here probably not statistically significant.

Interesting. There is a divergence under SMP versus UP. The hardware is the
same for both SMP and UP with the second cpu offline for UP. Maybe these will
start to make more sense with continued testing of newer kernels.
