Monitor debugger overhead

Last modified: 23 October 2024

Every time you evaluate an expression or step over the code, IntelliJ IDEA uses the same resources as the debugged application, and this may drastically impact the overall performance in particular cases. For example, breakpoints with heavy conditions may significantly increase the time required for a line of code to complete.

If the performance of the debugged application is not satisfactory, use the Overhead tab to find out which debugger features eat up most resources.

The Overhead tab provides you with the information about the number of hits and processor time used by each debugger feature. The view is updated dynamically, so you don't have to suspend your application to see the results.
