I would imagine most of the individual networker processes are single
threaded.  But having any number of single threaded jobs should not
cause a single CPU to be overloaded.  Any single threaded job will be
moved to different cpus by the scheduler over time.

You might want to run intrstat and see if anything obvious pops out of
it.  It shows interrupt statistics per CPU.  If one of your devices or
busses is generating an especially large amount of interrupts, it could
be overwhelming one of the CPUs.
