How performant is StackFrame?

I am considering using something like StackFrame stackFrame = new StackFrame(1) to log the executing method, but I don't know about its performance implications. Is the stack trace something that is build anyway with each method call so performance should not be a concern or is it something that is only build when asked for it? Do you recommend against it in an application where performance is very important? If so, does that mean I should disable it for the release?
