Performance characteristics sheet

Is there any place in the Unity documentation where detailed performance analyses of different methods and techniques can be found ? Since I have no access to the Unity source code it is hard to judge what is going on behind the scenes and what needs to be changed to make my game run at the best speed.

 

Unfortunately this kind of thing isn't really possible because of the huge number of combinations and permutations of hardware configurations, and looking at the source isn't likely to help much in and of itself.

The best way to deal with this is always to test various methods on your target platform(s) and see what works the best. For multi-platform stuff that requires high performance that might even require different implementations for different hardware to take advantage of its strengths.
