Yep, the debug tests indeed take more time, mostly because they run more checks.
Actually, the bigger cause in the slowdown is probably that debug tests don't have any optimizations, not more checks. An atomic increment on a debug build invokes something like a hundred instructions (including several call instructions) whereas the equivalent operation on an opt build is just one.
