I've seen a few tricks that you, Andrei, and others have used for 
profiling and optimization.

This naturally leads to "Is there a solid reference to this 
material in any shape form that isn't found by searching the 
forum"?

Optimization is an important aspect of coding. Having a 
collection of web pages, say wiki like, would be useful to many.

One of the main reasons I only lurk in D is because I do not 
currently have faith in being able to write high performance real 
time applications with it(mainly the GC). Being able to peruse 
some of the optimization strategies and tips that come up in the 
forum would be helpful, but not actually do this in the forum.

E.g., anyone care to start an "optimization" wiki for D?
