Can I turn off openplotter when loaded? - PaddyB - 2022-09-24

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  Cool

If all you are using OP for is updates consider installing & updating things from the command line. You seem to have the skills for that.

certainly an option once up and running but initially having openplotter set up repositories which work & play nice together could be handy
Though doesn't seem much difference in power...... about 5.3w or just over 6w with hifiberry playing back web radio. That's all running some usb/serial adptors & esp32 as well as the pi zero
