Control Window Synchronization

Correlate the data displayed in the
Bottom-up
window for each program unit (bottom-up analysis) and in the
Top-down Tree
window for an overall impact of each element together with its callees (top-down analysis).
The
Top-down Tree
window includes Self Time and Total Time columns for each data column in the
Bottom-up
window:
Top-down Tree Pane
In the Threading Efficiency example above, columns in the
Top-down Tree
window match the columns in the
Bottom-up
window as follows:
Bottom-up Window
Top-down Tree Window
Wait Time by Thread Concurrency
Wait Time: Total by Thread Concurrency
Wait Time: Self by Thread Concurrency
Wait Count
Wait Count: Total
Wait Count: Self
The
Bottom-up
window provides only
Self
type of data (function without callees). In the grid, Self time/Count column headers do not have
:
suffix
.
The
Total
type of data (function + all callees' Self data) is provided in the
<
data
>:Total
column and unique to the
Top-down Tree
window. In the example above, these are the
Wait Time:Total by Utilization
and
Wait Count:Total
columns.
Self time for a program unit in the
Bottom-up
window equals the sum of Self time values for the same program unit in different call sequences in the
Top-down Tree
window.
