I had truly hoped that was a quadcore device with a load of 4.87 4.97 4.68. So that means 4.87 average over the last minute, 4.97 average over the last 5 minutes, 4.68 average over the last 15 minutes. Where the a load of 1.0 is the equivalent of a single core at 100%
What 4.87 means on a single core like the pi is that 3.87 processes were waiting 100% for a minute, for that 4th process to finish and the rest to continue. So the system is 387% overloaded compared to what it can handle.
So the 11% displayed in the gauge looks a bit funny but chances are it’s so overloaded that it can’t properly update. Same for the temperature, 55 seems a bit low for 4.68 over 15 minutes.
