Newbie question (first post here)
I just put together all the components for a chartplotter (This is pretty cool!)
RPi 4B w/8gb ram
32 gb Micro that passes the speed tests
According to "top" Xorg and opencpn are consuming about 30-50% cpu each. Everything on the system is speedy and smooth except redrawing the chart
I downloaded the Full and High resolution GSHHG chart (I probably should delete the Full res chart, but how?
I have installed the dAISy hat and a GPS dongle but it was this slow prior to doing that.
Maybe this is normal but it takes
4 seconds to zoom in or out
2 seconds to draw a Measurement line (Tools -> Measure Distance)
