Optimum CPU performance
Pearl Nano is a dedicated single channel video encoder, recorder, and hardware streaming device;
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 the number of video sources, what frame
rate and bitrate is used for the channel, if the video output port 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.
For best results, we recommend keeping Pearl Nano's CPU usage under 70%.
