Performance Monitor

Invoking the menu Applications, Debug, Performance monitor adds a button to the status bar that displays performance information. Invoking it again will remove it.


Displays how much memory is allocated, and how much of that is available. For example, “Avail: 28% of 0.21GB”.

Pressing the button triggers a garbage collection.
