There's something funky here.

What are the numbers being factored in to 'will-it-scale.scalability'
and 'will-it-scale.per_process_ops'? Could you share the raw csv's that
will-it-scale generated?

Since 'per_process_ops' is only off by 1.1%, my suspicion is that some
consistent skew on the 1-process case is getting magnified in to the
scalability number.
