Multiple calls to 0-northeurope1-pushp.svc.ms
I have SPO tenant where I need to deploy JS customization. From time to time during debugging I notice that Edge browser is getting very laggy and slow. From my investigation it seems that it's caused by heavy traffic from SPO to something called https://0-northeurope1-pushp.svc.ms/socket.io/
Do you know what are those calls? What is this service and why those calls are made infinitely?

- Where are you deploying your JS files? If you use SPO cdns, you should not have speed problems when using your JS files
I'm deploying them to SPO Style Library. They're lightweight so it takes not more that 150ms to load them. But the problem are those calls from the screen - many times to the same location https://0-northeurope1-pushp.svc.ms/socket.io/
What are those? Some SP checks/pings/listener?
My 2 bits -
I think your best bet - Look at the features of socket.io https://github.com/socketio/socket.io (PS: svc.ms points to Microsoft)
