Hi there !
I'm facing a pretty big issue here. I have Node Red installed on a few RPi and a Qnap NAS. They are all working in a network and the NAS instance is the main one. For quite some time I've noticed that when I connect to the NAS Node Red instance from my PC (using firefox) the CPU usage skyrockets to nearly 100%, the browser freeze and I can't do anything.
I was wondering if someone knows about this problem and how to solve it. I precise that Yes, my Node Red instance is rather heavy... Lots of nodes, lots of tasks, etc... But really, why is my PC doing the CPU work ? Isn't it only supposed to display the nodes while the RPi/NAS does the work ? What I'm asking is what exactly my CPU has to process to go to 100% usage ?
