IntelliJ IDEA 2021.1 Help

Monitor IDE performance

In case of performance issues, you can use Activity Monitor to track the percentage of CPU consumed by various subsystems and plugins.

  1. From the main menu, select Help | Diagnostic Tools | Activity Monitor.

  2. The Activity Monitor window lists all subsystems and plugins that are consuming CPU at the moment and arranges them by how much %CPU they are using:

    Activity Monitor

If you notice increased CPU consumption, and no indexing or background processes are running at this moment, we recommend that you contact our technical support for assistance. Background processes are always displayed in the status bar at the bottom of the IDE window.
