So my flow has been running for a day and an hour and no performance dip and memory usage remains constant at 250mb. So it was the CPU and Memory nodes that were boging down the system. I will remove those two nodes and call it a success! So thank you for all the work you did and still doing . Your nodes are very important when dealing with SBCs!!  
Oh and I also ran a SSD1306 OLED display and no issues 🙂  
Thank you so much!!!
