Adding c++/cpu to the RT GPU mix slows my renders down ?

I did read this happening by someone else.

But wasn't the purpose of adding more resource to speed renders up ?

My GPU render took 6m 10s, whilst my GPU + CPU took 6m 42s....

If you have slow device (like CPU) and very fast GPU it might happen due to load balancing. It happens depending on the scene and it shouldn't be the average case.
So far we have one scene reported, but we still haven't the chance to look at it.
