These losses on the clock are hard to understand.  One possibility is that an
unexpected amount of time was consumed by events outside the engine.  This is
just speculation of course, but I wonder whether or not the engine programmers
made sufficient allowances for unexpected external events.

On the other hand, both engines may have significant bugs.

Could it be that the test setup itself has created this result?
