A hot package is any package in which an application spends a significant amount of time executing. It is a good place to start when looking for places in your code that can benefit from optimization.
The Hot Packages chart is comprised of a pie chart that graphically depicts the ratio of total recorded time the application spends executing in specific packages. The chart also contains a table that shows real numbers for the information shown in the pie chart. Notice that clicking an individual color on the pie chart highlights the associated package on the table. Table: Hot Packages Table Description describes the columns on this table.
Hot Packages Table Description
Column | Description |
---|---|
Package |
Name of the hot package. |
Sample Count |
The number of times, within the period specified in the range navigator, that the hotspot sampler ended up sampling a method in the package. |
Percentage |
The percentage of the total time, within the period specified on the range navigator, that the application spends in the package executing methods. |
You can customize the Hot Packages table (but not the pie chart) by using the context menu to do the following:
Change the sort order of each column. See Changing the Sort Order of a Table Column.
Select which data to show by selecting from a list of available columns.
Copy the selection for pasting elsewhere, for example in a text editor, and configure how that data is to be stored on your clipboard. See Copying Data to the Clipboard.
Add and remove individual data to and from the operative set.
