Asset Loading Profiler module
The Asset Loading Profiler module displays information about how your application loads assets, including a breakdown of read operations by area. The details pane provides an insight into each of the asset loading markers captured during the profile. You can use this information to determine how efficiently your application loads assets, and to identify any specific issues.
This module is not enabled by default. To enable the Asset Loading Profiler module, open the Profiler window, select the Profiler Modules dropdown menu, and toggle the Asset Loading checkbox.
图表类别
The Asset Loading Profiler module’s chart is divided into seven categories. To change the order of the categories in the chart, you can drag and drop them in the chart’s legend. You can also click a category’s colored legend to toggle its display. For more information on how to use the Profiler window, see Getting started with the Profiler window.

模块详细信息面板
When you select a frame in the Asset Loading Profiler module, the module details pane displays detailed information about how and when assets were loaded during the capture. This module can display information for either a single selected frame, or for all frames in the capture. Use the dropdown menu at the top-left of the details pane to choose between a single frame or all frames. This module doesn’t populate the details pane automatically. Instead, you need to select the Analyze Markers button at the top of the details pane to populate the view with data.
The Asset Markers view displays selected markers related to asset loading during the capture. Some rows have child markers that create a hierarchy, which is initially contained within a single expandable row. Select the dropdown arrow next to the marker’s name to expand the row and display all child markers.
The below table explains all of the possible columns that the Asset Markers view can display. Not all of these columns are enabled by default. To enable or disable a column, right-click anywhere in the row that contains the column names to open the column toggles sub-menu. Select any of the column names in this menu to either enable or disable that column. You can enter text into the search bar next to the Analyze Markers button to filter the results based on the Source column.
