Optimum CPU performance
Pearl-2, Pearl-2 Rackmount and Pearl-2 Rackmount Twin are powerful live video production systems;
however, there's a limit to the number of concurrent tasks the onboard CPU can perform efficiently.
The number of concurrent tasks depends on many factors, like: how many channels you have, how many
layouts you have per channel, how often you switch layouts, is the system resizing (scaling) video sources,
what frame rate and bitrate is used per channel, are the video output ports used, etc. Keep in mind that
connecting a live monitor to the HDMI output port consumes about the equivalent of an encoded
1920×1080@30 fps channel.
Streaming an NDI output consumes about the equivalent of an encoded 1920×1080@30 fps
channel on Pearl-2.
For best results, we recommend keeping Pearl-2's CPU usage under 70%.
