Well, it many cases it isn't the pure load numbers that are the
problem but the interaction of the behavior of actual real users.
   Like it isn't overly difficult to simulate a large volume of
traffic on a system, but it's extremely difficult to simulate
realistic behavior patters.  I think in many cases the problem
ends up being unexpected interactions of different behaviors that
cause problems rather than simply high volume.
