Optimum System Load

While Pearl-2 is powerful, there is a limit to the number of concurrent tasks the onboard CPU can perform efficiently.

The number of concurrent tasks depends on many factors, such as:

  • the number of video sources
  • what frame rate and bitrate is used for a channel
  • if the video output ports are used
  • if a live monitor is connected to the HDMI output port (about the equivalent of an encoded 1920×1080@30 fps channel)

Other limiting factors

  • how many channels you have
  • how many layouts you have per channel
  • how often you switch layouts
  • if the system is resizing (scaling) video sources

Streaming an NDI output with Pearl-2 consumes about the equivalent of an encoded 1920×1080@30 fps channel .

For best results, we recommend keeping System load usage under 70%.

Check CPU usage on the touch screen of Pearl Mini and Pearl-2

To check the CPU usage from the touch screen, tap the gear icon and select System Status.

Recommendations

If the system load is higher than recommended, you can:

  • Disable the video output port (if unused).
  • Remove unused channels or layouts.
  • Reduce the number of channels created.
  • Stop channel(s) that are streaming or recording.
  • Ensure video sources come in at the right resolution so that Pearl-2 doesn't have to up scale or down scale the video source.
