Back Traces view provides an inverted call stack showing all the call chains from where each node was called.
You can use these statistics to answer the question— How much time would I save if I eliminated this particular call chain from this node?
You can access the Back Traces view from any of the other snapshot views by right-clicking a node (known as the root node) and selecting Show Back Traces from the pop-up menu.
The Time and Invocations data values mean something different in Back Traces view:
Time: The values in this column represent the time spent in the root node when it is called from a given call chain.
Invocations: The values in this column represent how many times the root node was invoked from a given call chain.
