# Performance profiling

Remote Desktop Manager has a built-in profiler to diagnose connectivity issues with a workspace. Displaying the ***Performance profiling*** window might slow down the operations on the workspace. Proceed with care.

{% tab title="Windows" %}
To diagnose startup issues, enable the ***Performance profiling*** parameter from the command line as described in [Command line arguments](https://docs.devolutions.net/rdm/kb/how-to-articles/command-line-arguments/#usage-remotedesktopmanagerexe-parameters).

### Procedure

1. Select ***Help*** - ***Performance profiling***.

2. Once the ***Performance profiling*** is opened, ***Refresh*** the workspace. The data will appear in the window.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>Holding the <kbd>Ctrl</kbd> key while performing the refresh should force a full reload of the workspace, recreating the offline cache.</p></div>
3. Click on ***Send trace to support*** to send the data logs to our customer support team. Add a marker when running multiple tests to separate them.

#### Debug only

To learn more about the ***Debug only*** tab, please see [Debugging](https://docs.devolutions.net/rdm/kb/troubleshooting-articles/debugging/).

#### Auto mode

The ***Auto mode*** filters profiler output to only show operations that exceed a configurable time threshold (the ***Threshold (ms)*** field). This makes it much easier to spot slow operations without going through thousands of fast, normal entries.

Auto-mode entries are visually marked with a middle dot prefix (`·`) in the viewer so they are distinguishable from entries triggered by an explicit profiler level.
{% endtab %}

{% tab title="macOS" %}

### Procedure

1. Select ***Help - Performance profiling***.
2. Move the window to the side to display the Remote Desktop Manager main window and refresh the workspace by using the refresh button or by using ***File*** – ***Refresh***.

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>Holding the <kbd>Ctrl</kbd> key while performing the refresh will force a full reload of the workspace, thereby ignoring the cache.</p></div>
3. The Performance profiling data will appear in the window.
4. Click on ***Send Trace to Support*** to send the data logs to our customer support team. Add a Marker when running multiple tests to separate them.
