You optimize one thing, attribute access, by 25%, but you get an overall speed up of a factor of 6. How's that possible?

The benchmark test cases include overhead for object creation. That might skew the test results a bit.

Getters and setters aren't benchmarked individually. Instead, the benchmark tests call getters and setters an equal number of times. But in the Z Buffer Demo getters seem to predominate (based on a quick read the code). Intuitively, getters are going to be faster than setters, perhaps enough so to explain a factor of 6 improvement.
