This is not necessarily a processor problem.
Contentions for BUS, Memory, disks, etc can also cause slowdowns.
These can put a limit of things such as shared memory multi-processor
machines. In which case each process cannot easily get more power than
that of an equivalent single processor machine of the same type
anyway.
