I experience quite a performance breakdown in the middle of the day, when lots of whiteboards have been used. My idea was to use a nginx load balancer to split the requests up to multiple instances/servers. I open up two whiteboards (on 8080 and 8081) and use the config below. Then the whiteboards does not work any more. Strange thing ist, that a few lines get drawed, but very randomly. The cursor of other participants is not visible any more.

upstream backendwhiteboard {
	hash $request_uri;
	server localhost:8080;
        server localhost:8081;
server {
        server_name MYDOMAIN.XYZ;

        location / {
		proxy_pass http://backendwhiteboard;

Do you have an idea how to get a load balancer working?

Hi, Just wanted to let you know that I am currently working on some tweaks to increase the performances of this project (by changing some behaviors to reduce the number of messages and small websockets optimization). I’ll most likely open a PR tomorrow or Friday.
