Show HN: Please stress test this demo

I want to see how many browsers it can run before it becomes unresponsive. It's an 80 core 400 GB Skylake GCP instance running in Oregon. Logically it should be able to run 80 to 160, but at peak usage of around 60 I only saw about 5% utilization.

Stress test rules are you can't use a bot or script to do it, it has to be legitimate use to get an idea of what real peak looks like with websocket, browsing websites, bandwidth etc.

also running CPU workloads in JS won't work because the monitoring scripts will kill those users.
