What are the specs?
It's R Pi 3B, ARM-8 cortex A53, 1GB RAM and Rasbian OS.
It might be ok if you disable everything you don't need.
You have right, it works very well, even without disabling other things.
Needed steps to work:
I have it running on a Pi3 , the same server also runs openmedia vault, so it can be done
Does anyone have experience with running Traccar server newest version 5.x on older Rapsberry, like Model 3B or 3B+? Is it worth trying?
