What I'm finding is that CPU usage is pretty good when there is no NMEA going in. In my case, if I turn off AIS and GPS inputs, the CPU usage drops down to a pretty reasonable level, even when I'm using MBTiles charts.
OTOH, if I start feeding AIS and/or GPS nmea strings into it, the total CPU usage for just OpenCPN goes to around 360% and stays there. In the case of AIS, even after I stop the incoming NMEA coming in, the CPU usage stays the same, presumably until the AIS times out (I'm not patient enough to wait...).
You can open a terminal window and use the "top" command to get a good idea of what processes are using CPU and memory in real time.
