 ===== Profiler Layout =====

+{{ tutorials:tools:profiler-layout.png?direct |}}
 ==== 1) Thread Frame bar ====
-This grey bar indicates which thread is currently selected. Most of Orx's tasks run on the main thread. There are other threads that handle things like streaming audio, resource requests and bitmap decompressing which run on other threads. Select your thread with the ''Page Up'' and ''Page Down'' keys.

 The first value displayed is the amount of time in ms that it took to render the entire current frame. The second value shows the largest amount of time that a frame took to render in the last second.
 ==== 2) The Meter Bar Panel ====
-These colored meter bars indicate how much time each Marker took to complete within the frame. The colors themselves correspond to the colors on each Markers in the Marker panels.

+{{ tutorials:tools:profiler-colours.png?direct |}}
 The bars are spread over four or more lines. The row of the bar corresponds to the level of the function call marker. For example, the ''orxRender_RenderAll'' function call is on the top level, so sits in the top row. The ''orxRender_RenderObject'' function call is three levels into the hierarchy and is therefore on the third row.

 This helps easily distinguish between the markers that are of similar color.

 ==== 3) Marker Panel ====
 This panel shows all the Markers currently running in the frame. Markers represent important function calls. Each Marker contains three numbers.
+{{ tutorials:tools:profiler-markers.png?direct |}}
 The first is the amount of time in ms this Marker has taken to run in the current frame. The second number indicates the longest amount of time this Marker took to run in the last second.

 The Markers in this panel are white and have more than one parent. Therefore they don't fit in to the tree hierarchy.
-There can be grey markers in this panel as well for the same reason as the Marker Panel above.

+These markers can be grey in this panel as well for the same reason as the Marker Panel above.
 ==== 5) Memory Panel ====
 Each line represents a different type of memory.
+{{ tutorials:tools:profiler-memory.png?direct |}}
 The first group of numbers represents the number of live allocations and the second number is the max allocations in the past.
-The second group of numbers is the same, but is now representing the size of the memory allocations in Megabytes.

 The last number shows the amount of transactions since the beginning of the application. A transaction is the allocating or de-allocating of memory.

-Notice that the ''orxPhysics_ApplySimResult'' marker appears now in the Marker Panel. And there is a corresponding colored meter bar for it in the Meter Bar Panel. Once all the objects have finished their lifetime and have disappeared, then the ''orxPhysics_ApplySimResult'' marker drops down to grey again and is no longer called.

 You can profile an application with vsync on or off. In the playground application you can toggle this with the `F11` key. With vsync on, the longest bar will be the ''orxDisplay_Swap'' marker. This is not Orx working hard on a task, but rather the driver wait time for the next vertical sync.

 ===== History Graph =====

+And that is the Orx Profiler. This tool should be invaluable for checking the health of your application and to help you optimize it.
+===== Choosing the Profile Orientation =====
+The Profiler orientation can be set as either portrait or landscape. Landscape is the default. You can see the ''ShowProfiler'' and ''ProfilerOrientation'' properties available for the Profiler in the [[en:orx:config:settings_main:main#render_module|Render Config Properties]]:
+{{section>en:orx:config:settings_main:main#[summary11]&noheader&nofooter&noeditbutton}}
+You can set to portrait with:
+<code=ini>
+[Render]
+ProfilerOrientation = portrait

+This rotates the profiler to the left, perfect for portrait monitors.
