Thanks to the resources of the OSDL (http://www.osdl.org) I now can generate 
benchmarks for the same hardware in UP and SMP modes. Here are the current 
stable kernel benchmarks with contest (http://contest.kolivas.net):

io_other is a custom addition which performs an io_load on a different hard 
disk from where the kernel compilation is.

Slowdown under IO load on same and other disks, and xtar load. Speedup with 
dbench load and read loads.
