1 / 5
In a flame graph, the ___ of a frame represents how much time was spent in that function and its children.

2 / 5
The vertical axis (stacking) of a flame graph shows the ___.

3 / 5
Time spent in a function's own code, excluding its callees, is its ___ time.
-

4 / 5
The widest top-level path you'd optimise first is often called the ___ path.
-
-
-
-
The hot path is where most time is spent; optimising it yields the biggest performance gains.
5 / 5
In a flame graph, frame colours are typically ___ rather than meaningful.
-
-
-

Colours in a standard flame graph are usually random for visual separation; width and stacking carry the real information.
