I am running Node-RED on an embedded computer with limited resources. I have developed a set of flows for my application. With all flows loaded into the editor, a browser refresh takes about 20-30 seconds to refresh and redraw the editor interface and my flows. I created libraries of each of the five flow pages I have using the Export->Library function in the editor. Now it takes over 8 minutes to refresh the Node-RED editor in a browser window! I removed the library files and it returned to the 20 second refresh time.
What is Node-RED doing with libraries on a browser refresh? Why would a static library file, that is just stored on the system for possible use at a later time, cause Node-RED to take so much longer to redraw the screen?
