A single pi4 has an impressive amount of processing power...

In my day job I'm a .net and react guy and I made a proof of concept for a next version of a possible product (tech preview, to show the people that their estimates were just insane - on the high side) on a pi 4, running in .net core on manjaro on my pi4.. this is a fairly intensive thing, using signalR with lots of messaging going on and cpu usage is ~10% at peak...

So.. my next task will be to run that on solar too :D
