The confusing thing is that I thought 'real' time should be >= 'user' + 'sys'.
But here 'user' is much greater than 'real' for both machines! The sense I
got from the other messages in this thread is that 'user' time is somewhat
meaningless (i.e. unreliable as a measure) in a multi-CPU and/or hyperthreading
environment. Can you clarify?
real >= (user + sys) * ncpu

umm, other way around of course.

real * ncpu >= (user + sys)
