Performance module

The Performance module lets you monitor your computer’s performance, including CPU, disk and memory activity.

To show/hide the Performance module

Right-click the Control Bar and select Performance Module.

The Performance module contains the following controls:

CPU meters. Displays the time it takes to process a buffer full of audio data as a percentage of the maximum time available to process that data and maintain uninterrupted playback. There is one CPU meter for each core in your computer, up to 32 cores. There is some tolerance built into the meter, so it is possible that it will exceed 100% at times (more so during recording than playback).

Note: The width of the Performance module depends on the number of CPU cores available.

Disk Activity indicator . Measures how much of the available time SONAR is using to perform input/output functions on your hard disk. The size of your setup’s I/O buffer size (listed under File System in Edit > Preferences > Audio - Sync and Caching) determines how much time is allowed to perform disk operations and maintain uninterrupted playback. When SONAR performs disk operations, the Disk Activity indicator changes color from yellow to red to indicate the time SONAR is taking to complete each cycle of disk input/output. A red icon indicates very high data activity.

Disk Space meter. Shows the amount of available space on the drive where your wave data directory is located. The tooltip shows the actual remaining disk space on your audio disk.

Memory Usage (RAM) meter. Shows the total memory (RAM) usage by your computer, not just by SONAR.

Note: If you experience a dropout or your CPU or Disk meters are reading high, there are steps you can take to improve your audio performance. For more information, see Audio dropouts or crashes during playback.
