Playing around onboard this morning to see how much I can turn off to lower the load on a PiZero2W..
So far.. sudo systemctl stop(&disable)-- vnc server, lightdm, gpsd..
This leaves influx & signalk & grafana among others --
So - plan is enable again & use openplotter/vnc to load/update software then all off again when up and running.
Will this cause any problems I might come across later? Or any other stuff I could turn off?
Load average 2 minute seems to be down around 0.4 when it settles down.
TIA
