Also, looking at that screenshot, it looks like your harvester may be loading plots every other minute or so. I am not sure what kind of setup gigahorse for chia has, but you may want to check what kind of plot refresh rate you have there for your harvester. You would want to set it up for about an hour or longer, as those plot loads can be heavy on the system. If you are plotted, there is no problem to have it once a day or so.
