RTL-AIS app 2 processes in htop

[jamos.tan@gmail.com]

Hi,

I am using the openplotter AIS app. I know that SDR will demand CPU usage, but I want to check something.
When opening htop I see two processes:



Isn't it supposed to be 1 process? Or is this some sort of load balancing accross cpu cores?
Anyway, it does seem to slow down the Pi, although total CPU load is around 24 in total.

Anybody got any ideas?

rtl_ais listen to both AIS channels. I may be wrong but it could be a process for each channel.
