depth-first-search

I'm writing a component that needs to walk large object graphs, sometimes 20-30 levels deep.

What is the most performant way of walking the graph?

A. Enqueueing "steps" so as to avoid deep recursion

or

B. A DFS (depth first search) which may step many levels deep and have a "deep" stack trace at times.

I guess the question I'm asking is: Is there a performance hit in .NET for doing a DFS that causes a "deep" stack trace? If so, what is the hit? And would I better better off with some BFS by means of queueing up steps that would have been handled recursively in a DFS?

Sorry if I'm being unclear. Thanks.
