Oh yes, that would really be nice. Knowing when to write custom snippets instead of using getResources, how to make those snippets fast (with Xpdo), when to use output modifier instead of IF-snippet, or perhaps none of those? Use resource filtering based on a TV, good or slow? Making a separate table, fast or slow? Fastest way of querying it? And so on...
Modx is fantastic in the way you can do everything in many ways to get to where you want, but only one solution can be the optimal.
So, a general guide for optimization would be optimal.

With lots of general examples.
Or perhaps at least a dedicated part of the forum for this so it would be easy to find discussions about best ways of doing stuff.
