Firefox/Chromium incredibly slow

[hcsaustrup]

We're using Terraform to orchestrate Kubernetes infrastructure with a major cloud provider, and the generated plan.json file is just over 17MB. When accessing the Rover web server, both Firefox and Chromium uses 100% of one core and completely grinds to a halt. I've left it for about 20 minutes now, and the only thing that is happening is that I get warnings about the browsers being unresponsive.

This is with the latest version pulled from docker.io.

Output:

$ podman run --rm -it -p 9000:9000 -v "$(pwd)/plan.json:/src/plan.json" docker.io/im2nguyen/rover:latest -planJSONPath=plan.json
